Question

The length of a rectangular floor is 20 m more than its breath.if the perimeter of the floor is 280 m. What is its length

Answer 1

Answer:Length is 80m

Step-by-step explanation:

Let the breadth of the floor be x

Length  = x+20

Perimeter= 2(l+b)

280= 2(x+20+x)

280/2= 2x+20

140-20= 2x

x= 120/20= 60

Therefore, the length is x+20= 60+20=80m and width is 60m
