Answer 1

Hi ,

let the dimensions of the each rectangle

length = l cm

breadth = b cm

according to the problem given,

perimeter of the rectangle = 48 cm

2 ( l + b ) = 48

l+b = 24 cm -----( 1 )

But side of the square = length of the

rectangle = 5 × breadth of the rectangle

l = 5b ---( 2 )

put l = 5b in equation ( 1 )

5b + b = 24

6b = 24

b = 24/6

b = 4 cm

l = 5b = 5 × 4 = 20 cm

Therefore ,

side of the square = l = 20 cm

perimeter of the square = 4l

= 4 × 20

= 80 cm

option ( D ) is correct

I hope this helps you.
