Question

Find the length and breadth of the rectangle given below if it's perimeter 7.2m or length is 5x+4 and breadth is x-4​

Answer 1

Answer:

so we take 2(l+b)=p

so

Step-by-step explanation:

so 2(5x+4+x-4)=7.2m

10x+8+2x-8=7.2m

12x=7.2m

so x=7.2÷12

x=0.6m

so length=5×0.6+4=3+4=7

so length=8m

so breadth=0.6-4=-3.4
