Question

The combined area of the two circles is 308 square cm. Find the perimeter of the rectangle. Take π = 22/7.​

Answer 1

Answer:

Area of two equal circles is 2π * r ^ 2

2×22/7× r× r=3

r^ 2 =308/2×7/22

r^ 2 =49

r= √49=7cm

Now,

2r = diameter of circle = length of rectangle

length =14 cm

radius of circle= breadth of rectangle = 7cm

Perimeter of angle = 2(l + b)

=2(14+7)

The perimeter of the rectangle is 42 cm

=2*21=42cm
