Question

the perimeter of a rectangle is equal to that of a square with side 13 m if the rectangular is 16 m long what is its breadth

Answer 1

Perimeter of rectangle = perimeter of square.

2 ( l + b) = 4 × side.

2 ( l + b) = 4 × 13

2 (16 + b) = 52

16 + b = 52/2

16 + b = 26

B = 26 - 16

= 10 cm.
