What is the Anwser

Question

a rectangle has an area of 30 square meters and a perimeter of 34 meters what are the dimensions of the rectangle

Answer 1

A=lxb=30

b=30/l

P=2(l+b)=34

Substituting for b we have

2(l+30/l)=34

l^+30=17l

l^2-17l+30=0

l^2-15l-2l+30=0

(l-15)(l-2)=0

l=15 or l=2

b=30/l

b=2 or b=15

The dimensions of the rectangle are 15m(length) and 2m (breadth).
