Question

Area of circle is equal to area of rectangle having perimeter of 50cm and the length is more than its breadth by 3cm. what is the diameter of the circle

Answer 1

Let the width be w and the length be w + 3

Perimeter = 2l + 2w

Where l is the length and w the width.

From the question Perimeter will be %

2w + 2(w + 3) = 50

2w + 2w + 6 = 50

4w = 50 - 6

4w = 44

w = 11

Length = 11 + 3 = 14

Area of rectangle = 14 × 11 = 154

Area of the circle = 22/7 × r²

Where r is the radius

Area of circle = Area of rectangle

154 = 22/7 × r²

r² = 154 × 7/22

r² = 49

r = √49

r = 7

Diameter = 2r

Diameter = 2 × 7 = 14cm
