Question

the length of a rectangle is three times its width. if the perimeter is 72m,find the length and breadth of a rectangle

Answer 1

GIVEN :

The perimeter of the rectangle = 72 m

Let the breadth be x
Then length = 3x


SOLUTION :

2 (l +b) = 72m

2(3x+x)= 72

6x+2x = 72
8x =72

X = 72 /8

X= 9
Breadth =9 m
Length = 3 X x= 27
