Question

If the ratio of the length to breadth of a rectangle be 5:3 and it's perimeter is 144 m, find the length of a rectangle.​

Answer 1

Answer:

THE LENGTH OF RECTANGLE IS 45m!!!

Step-by-step explanation:

PARAMETERS GIVEN,

RATIO OF LENGTH TO BREADTH = 5:3

PERIMETER OF RECTANGLE = 144m

SO,

LET THE COMMON RATIO BE x

SO,

LENGTH = 5x

BREADTH = 3x

SO,

A.T.Q.,

PERIMETER = 2(LENGTH+BREADTH)

144m=2(5x+3x)

144m=2*8x

144m=16x

x=144m/16

x=9m

SO,

LENGTH = 5x = 5*9m = 45m

I HOPE YOU UNDERSTOOD THE QUESTION!!!
