Question

The area of a rectangle is `(y^2-8y+15)` square inches. What is the length and width of the rectangle?

Answer 1

Length = 5", Width = 3"

Explanation:

Given `y^2 - 8y + 15 = A`

`y^2 - 3y - 5y + 15 = A`

`y (y-3) - 5 (y-3) = A`

`(y-5) * (y-3) = A`

`:.` length`= b = 5", width = h = 3"`
