Question

A rectangle has an area of 30 square meters and a perimeter of 34 meter. What are the dimensions of the rectangle?

Answer 1

Rectangle's Perimeter is P=2(w+l)
where w and l are width and length respectively
34=2(w+l)
17=w+l
w=17-l

now A=wxl
A=(17-l)xl
A=17l-l^2
30=17l-l^2
l^2-17l-30=0

now solve for l
