Question

the length of a rectangle floor is 30 M more than its breadth if the perimeter of the floor is 340 square metres what is its length​

Answer 1

Breadth be x
Length =x+30
Perimeter=340
2(l+b) =340
2(x+30+x)=340
2(2x+30)=340
4x+60=340
4x=340-60
4x=280
X=280/4
X=70

Hence,length =30+b
=30+70=100 m
