Question

if the ratio of length to the breath of rectangle
be 5:3 and its perimeter is 144 meter
find the length of
rectangle​

Answer 1

Answer:

81 meters

Step-by-step explanation:

let length=5x

breadth=3x

perimeter=2(l+b)

2(5x+3x)=144 meter

2(8x)=144

16x=144

x=144/16

x=9

length=5x=5•9=81 meters
