Question

the length and breadth of a rectangle are are in the ratio 5: 3 find the dimension of rectangle if its perimeter is 112​

Answer 1

Ratio = 5:3

let,

Length = 5x

Breadth = 3x

P = 2 (l+b)

112 = 2 (5x+3x)

112 = 2 ×8x

112 = 16x

x = 112/16

x = 7

Length = 5 × 7 = 35

Breadth = 3 ×7 = 21. Ans
