Question

The length of a rectangle is 2 more than twice the width. The area of the

rectangle is 60. Find the dimensions of the rectangle. What is the length of
the rectangle?

Answer 1

Answer: w=5 , L= 2+2(5)=12

Explanation:

L=2+2W

A= 60

LxW=60, now we will replace the L

(2+2W)(W)=60 we multiply

2w^2+2w=60

2w^2+2w-60=0 we divide by 2 the equation so we can work easier

w^2+w-30=0

find out w using the quadratic equation

we will get 2 solution,

w=5 and another solution is -6, which is not valid, as the side can not be negative
