Question

The area of a opening rectangular window is to be 440 square centimeters. If the length measures x centimeters and the width measures x-2 centimeters, what are the dimensions?

Answer 1

`L=1+20i`

`B=3+20i`

Explanation:

From the question we are told that:

Area
`A=440cm^2`

Generally the equation for For Area is mathematically given by

`A=L*B`

`A=x*(x-2)`

Therefore

`x^2-2x-440=0`

`x=1+20i`

Therefore The Dimensions are

`L=1+20i`

`B=1+20i+2`

`B=3+20i`
