Question

The perimeter of a rectangle is 39 cm. And the ratio of its adjacent sides is 5:8, find the length of rectangle .

Answer 1

Answer:

length of rectangle=15/2cm.

breadth of rectangle=12cm

Step-by-step explanation:

perimeterof a rectangle=39cm

ratio of its adjacent sides =5:8

let l=5x, b=8x

perimeter=2(l+b)

39=2(5x+8x)

39=2×13x

39=26x

x=39/26

x=3/2

l=5×3/2=15/2cm

b=8×3/2=12cm
