Question

the length of the rectangle is two and a half times its width. if the perimeter of the rectangle is 84m , then find its dimension.​

Answer 1

Step-by-step explanation:

let width be X and length be 3x/2

2(l+b)=84

2(X+3x/2)=84

2(5x/2)=84

5x=84

X=16.8

So width is 16.8m and length is 25.2m
