Question

Find the length and breadth of the

rectangle given below if its perimeter is

72m. where length is 5x+4 and

breadth is x-4 m

with full explanation​

Answer 1

Step-by-step explanation:

perimeter= 72 m

length l= 5x+4

breadth b= x-4

formula of perimeter= 2(l+b)

2[5x+4+x-4]= 72

6x= 72/2

6x= 36

x= 36/6

x= 6

Lenght= 5x+4= 5*6+4=34 m

breadth= x-4=6-4=2 cm

perimeter= 2(34+2)=72 m
