Question

The length of a rectangle. Floor is 20m , more that it's breadht . If the. Preimeter Of the floor is280m what is its length

Answer 1

Answer:

Let breadth of the rectangle be x m

length = 20+x

Perimeter=280m

2(l+b)=280

2(20+x+x)=280

20+x+x=280/2

20+2x=140

2x=140-20

2x=120

x=60

breadth of the rectangle=x=60m

length of the rectangle=20+x

=20+60=80m

breadth is 60m and length is 80m.
