Question

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

Answer 1

Answer:

ATQ

length be 5x and breadth be 3x

it's perimeter is 128m

2(l+b) = 128m

2(8x) = 128m

x = 8

thus length is 5 x 8 = 40m

and breadth is 3 x 8 = 24m

hope this will help you

Answer 2

Answer:

length:breadth = 5:3

let common multiple me x

therefore length =5x

and breadth =3x

perimeter of rectangle=2(length+breadth)

128=2(5x+3x)

128/2=8x

64=8x

x=64/8

x=8m

length = 5x = 5*8=40m

breadth=3x=3*8=24m
