Test: Perimeter and Area - Class 7 MCQ

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. 

The formula for the circumference of a circle is:

Circumference = π × diameter

Circumference = 3.14 ×10 = 31.4cm

Since Area of parallelogram is base × height

So Height = Area of parallelogram / Base 

So option A is the correct answer. 

- The distance around a circular region is known as its circumference.
- Circumference is the term used to describe the perimeter of a circle.

Area of parallelogram = Base × Height

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. 

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.
