Test: Perimeter and Area - Question 1

The area of a rectangular sheet is 500 cm2. If the length of the sheet is 25 cm, what is its width?

Detailed Solution for Test: Perimeter and Area - Question 1

Area = Length × Width

Width = Area / Length
= 500 cm² / (25 cm)
= 20 cm

So option A is the correct answer. 

Test: Perimeter and Area - Question 2

If the area of rectangle increases from 2 cm2 to 4 cm2 the perimeter will

Detailed Solution for Test: Perimeter and Area - Question 2

If the area of rectangle increases from 2 cm2 to 4 cm2 the perimeter will also increase.

Test: Perimeter and Area - Question 3

The area of a square whose perimeter is 4 m

Detailed Solution for Test: Perimeter and Area - Question 3

Since it is given that perimeter of a square is 4m

We know that Perimeter of a square = 4a

 So, 4a = 4 

it implies that a = 1 

Area of a square =  a2

As a = 1 (as calculated above)

So area of a square = 1 m2

So option B is the correct answer. 

 

Test: Perimeter and Area - Question 4

 Which figure encloses more area: a square of side 2 cm ; a rectangle of side 3 cm and 2 cm ;An equilateral triangle of side 4 cm?

Detailed Solution for Test: Perimeter and Area - Question 4

Area of a square = a2 = (2 x 2) cm2
=  4 cm2

Area of rectangle =  L X B
= (3 x 2 ) cm2
= 6 cm2

Area of an equilateral triangle = root 3/4 .a2
= root 3/4 × (4)2
= 1.732 / 4 × 16
= 0.433 × 16
= 6.928 cm2

Since the area of  an equilateral triangle is more than area of a square and rectangle. So equilateral triangle encloses more area

So option A is the correct answer. 

 

 

Test: Perimeter and Area - Question 5

The area of rectangle whose length is 15 cm and breadth is 6 m

Detailed Solution for Test: Perimeter and Area - Question 5

Area of a rectangle is Length x Breadth

Here Length is 15 cm and Breadth is 6 m

We know that 1 m = 100 cm

So 6 m = 600 cm2

So area of a rectangle =(15 x 600 ) cm2

                                            = 9000 cm2

                         

 

Test: Perimeter and Area - Question 6

By converting 0.96km² into m²(meter square), answer will be

Detailed Solution for Test: Perimeter and Area - Question 6

1 Square kilometer is equal to 1000000 square meters

therefore,
0.96km² =  960000m2 

Test: Perimeter and Area - Question 7

The area of parallelogram is

Detailed Solution for Test: Perimeter and Area - Question 7

The area of parallelogram is base × height

So option B is the correct answer. 

Test: Perimeter and Area - Question 8

The base in the area of parallelogram is

Detailed Solution for Test: Perimeter and Area - Question 8

Since area of parallelogram is base × height

So to find Base of parallelogram the formula is = Area of parallelogram / Height

So option A is the correct answer. 

Test: Perimeter and Area - Question 9

The height in the area of parallelogram is

Detailed Solution for Test: Perimeter and Area - Question 9

Since Area of parallelogram is base × height

So Height = Area of parallelogram / Base 

So option A is the correct answer. 

Test: Perimeter and Area - Question 10

Which of the following has the formula : Base × Height

Detailed Solution for Test: Perimeter and Area - Question 10

Area of parallelogram = Base × Height

Test: Perimeter and Area - Question 11

Find the area of a triangle with a base of 20 cm and a height of 30 cm

Detailed Solution for Test: Perimeter and Area - Question 11

We Know, Area of a triangle is bxh/2

where b is base and h is height

Given that base is 20cm  and height is 30cm

So Area of a triangle 20 cm x 30cm / 2

= 600 cm2/2     

= 300 cm2

So option A is the correct answer. 

 

Test: Perimeter and Area - Question 12

What is the area of the circle of radius 5 cm 

Detailed Solution for Test: Perimeter and Area - Question 12

The formula to calculate the area of a circle is

A=πr2

This means that if r=5cm, the area is

A=52π cm2=25π cm2≈78.539816 cm2

Test: Perimeter and Area - Question 13

Find the perimeter of a square with one side equals to 7cm

Detailed Solution for Test: Perimeter and Area - Question 13

We know Perimeter of a square is 4a 

= 4 x 7cm 

= 28 cm 

Test: Perimeter and Area - Question 14

Find the perimeter of a triangle with sides 4 cm, 6 cm and 10 cm

Detailed Solution for Test: Perimeter and Area - Question 14

 

Perimeter = Sum of all the sides 

Perimeter of a triangle = a+b+c

Here a = 4cm , b = 6cm , c =10cm

(6+4+10)cm=20cm

So option A is the correct answer. 

Test: Perimeter and Area - Question 15

 Find the perimeter of the quadrilateral with sides 5 cm, 7 cm, 9 cm and 11 cm.

Detailed Solution for Test: Perimeter and Area - Question 15

The sum of the length of all the four sides of the quadrilateral is called the perimeter of the quadrilateral.

Here the lengths of all the four sides are 5 cm, 7 cm, 9 cm and 11 cm.

Therefore, perimeter of quadrilateral = 5 cm + 7 cm + 9 cm + 11 cm = 32 cm

So option A is the correct answer. 

                                         

Test: Perimeter and Area - Question 16

Find the area and perimeter of a rectangle whose breadth is 4 cm and the height 3 cm.

Detailed Solution for Test: Perimeter and Area - Question 16

Area = b×h = 4×3 = 12 cm2.
Perimeter = 2(b) + 2(h) = 2(4) + 2(3) = 8 + 6 = 14 cm
