Question

Find the length and breadth of the rectangle given below if its perimeter is
72m.
5x+4
X-4​

Answer 1

Step-by-step explanation:

Perimeter of rectangle = 72m

Length of rectangle = 5x + 4

Breadth of rectangle = x - 4

Perimeter of rectangle = 2( l+b )

72 m = 2 ( 5x + 4 + x - 4 )

72 m = 2 ( 5x + x )

72 m = 2 ( 6x )

72/2 = 6x

36 = 6x

36/ 6 = x

6 = x

length = 5x + 4 = 5×6 + 4 = 34 m

breadth = x - 4 = 6 - 4 = 2m
