The area of a rectangle is 299 cm. The length is 3 cm less than twice the width. What are the dimensions of the rectangle? Must show all work

Answer 1

First of all, I assume you mean 299 cm².

W = width; L= length

L = 2W - 3

Area = W(2W-3) = 299

2W² - 3W - 299 = 0

Use the quadratic formula to get an extraneous root and W = 13

You get L!
