Question

Find the length and breath of the rectangle given below if the perimeter is 72 cm
x +4
5x - 4​

Answer 1

Answer:

Let the breadth be x+4 and length be 5x-4

Perimeter of rectangle is 72cm

2(l+b)=72

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

6x=36

x=6

Substitute x value to get length and breadth.

breadth=x+4

=>10cm

length=5x-4

=>26cm
