Question

the length and the breadth of a rectangular field are in the ratio 5:3 if it's perimeter is 128m, find the dimensions of the field. ​

Answer 1

Answer:

Length = 40 m

Breadth = 24 m

Step-by-step explanation:

Let,

length be 5x m

breadth be 3x m

Perimeter = 128 m

A/Q

Perimeter = 2(l+b)

128m = 2( 5x + 3x )

128/2 = 8x

64/8 = x

8= x or x = 8

Hence, Length = 5 × 8 = 40 m

Breadth = 3 × 8 = 24 m
