Detailed Solution for Mensuration - MCQ 2 - Question 9

Circumference of the circle = 132
2πR = 132; R = 21 cm
Side of square = 21 cm
Length of the rectangle = 3/5 * 21 = 63/5
Area of the rectangle = 63/5 * 15 = 189 cm²

Mensuration - MCQ 2 - Question 10

Detailed Solution for Mensuration - MCQ 2 - Question 10

Side of square = 72/4 = 18 cm
Smallest side of the right angled triangle = 18 – 13 = 5 cm
Length of rectangle = 112/8 = 14 cm
Second side of the right angled triangle = 14 – 2 = 12 cm
Hypotenuse of the right angled triangle = √(25 + 144) = 13cm

In a rectangle the ratio of the length and breadth is 3:2. If each of the length and breadth is increased by 4m their ratio becomes 10:7. The area of the original rectangle in m² is?

Detailed Solution for Mensuration - MCQ 2 - Question 11

[3x + 4 / 2x + 4] = 10/7
x = 12
Area of the original rectangle = 3x * 2x = 6x²
Area of the original rectangle = 6 * 144 = 864m²

Mensuration - MCQ 2 - Question 12

The perimeter of a rectangle and a square is 160 cm each. If the difference between their areas is 500 cm. If the area of the rectangle is less than that of a Square then find the area of the rectangle?

Detailed Solution for Mensuration - MCQ 2 - Question 12

Perimeter of rectangle = Perimeter of Square = 160
4a = 160 ⇒ a = 40 Area of square = 1600
1600 – lb = 500
lb = 1100 cm²

Mensuration - MCQ 2 - Question 13

Circumference of a circle A is 22/7 times perimeter of a square. Area of the square is 441 cm². What is the area of another circle B whose diameter is half the radius of the circle A(in cm²)?

Detailed Solution for Mensuration - MCQ 2 - Question 13

Area = 441 cm²
a = 21 cm
Perimeter of Square = 4 * 21
Circumference of a Circle = 4 * 21 * 22/7
2πr = 4 * 3 * 22
r = 12 * 22 * 7 / 2 * 22 = 42 cm
Radius of Circle B = 42/4 = 10.5 cm
Area of Circle = πr² = 22/7 * 10.5 * 10.5 = 346.5 cm²

Mensuration - MCQ 2 - Question 14

The area of a rectangle is equal to the area of a square whose diagonal is 12√2 metre. The difference between the length and the breadth of the rectangle is 7 metre. What is the perimeter of rectangle ? (in metre).

Detailed Solution for Mensuration - MCQ 2 - Question 14

d = a√2
12√2 = a√2
a = 12
l * b = a² = (12²) = 144
l – b = 7 ; l = b + 7
(b + 7)*(b) = 144
b² + 7b – 144 = 0
b = 9; l = 16
2(l + b) = 2(16 + 9) = 50m

Mensuration - MCQ 2 - Question 15

The area of a rectangle gets reduced by 9 square units,if its length is reduced by 5 units and breadth is increased by 3 units. If we increase the length by 3 units and breadth by 2 units, then the area is increased by 67 square units. Find the area of the rectangle?

Detailed Solution for Mensuration - MCQ 2 - Question 15

Length = x; Breadth =y
xy – (x-5)(y+3) = 9
3x – 5y – 6 = 0 —(i)
(x+3)(y+2) – xy = 67
2x + 3y -61 = 0 —(ii)
solving (i) and (ii)
x = 17m ; y = 9m
Area of the Rectangle = 153 m

Mensuration - MCQ 2 - Question 16

The length of a plot is four times its breath. A playground measuring 900 square meters occupies one fourth of the total area of a plot. What is the length of the plot in meter.?

Detailed Solution for Mensuration - MCQ 2 - Question 16

Area of the plot = (4 x 900) m²
= 3600 m²
Breadth = y meter
Length = 4y meter
Now area = 4y x y = 3600 m²
⇒ y² = 900 m²
⇒ y = 30 m
∴ Length of plot = 4y =120 m

Mensuration - MCQ 2 - Question 17

The sum of the radius and height of a cylinder is 19m. The total surface area of the cylinder is 1672 m², what is the radius and height of the cylinder?(in m)

Detailed Solution for Mensuration - MCQ 2 - Question 17

r + h = 19 m
2πr(r + h) = 1672
r = 1672 * 7/ 2 * 22 * 19 = 14
r = 14 ; h = 5

Mensuration - MCQ 2 - Question 18

If each side pair of opposite sides of a square is increased by 20 m, the ratio of the length and breadth of the rectangular so formed becomes 5:3. The area of the old square is?

Detailed Solution for Mensuration - MCQ 2 - Question 18

(x+20) / x = 5 / 3
3x + 60 = 5x
x = 30m; Area = 900m²

Mensuration - MCQ 2 - Question 19

The length of a park is four times of its breadth. A playground whose area is 1024 m² covers 1/4th part of the park. The length of the park is?

Detailed Solution for Mensuration - MCQ 2 - Question 19

l = 4b
Area of the park = 4 * 1024 m²
l * b = 4 * 1024
l * l/4 = 4 * 4 * 1024
l² = 1024 * 16; l = 32 * 4 = 128 m

Mensuration - MCQ 2 - Question 20

The width of a rectangular piece of land is 1/4 th of its length. If the perimeter of the piece of land is 320 m its length is?

Detailed Solution for Mensuration - MCQ 2 - Question 20
