Question

The length and the breadth of a rectangular field are in the ratio 5 : 4 .If its perimeter is 108 m find the dimensions of the field




I don't understand this question
how to solve it plz help me.

Answer 1

5x+4x =108
9x=108
x=108/9

solve it


find x later apply on 2(l+b)

Answer 2

Perimeter of rectangle = 2 ( l+b)
Now ,let the sides of rectangle are 5x and 4x
108 m = 2( 5x+ 4x)
108 = 2(9x)
108 = 18x
108/18 = x
6 = x
Now , dimensions of rectangle are
5x =5*6=30m
4x =4*6=24m
