Question

The length of a rectangular dassroom floor is

19 feet less than twice its width. write an
expression to represent the area of the floor
in simplest form.

Answer 1

W(2W-19)

Explanation:

let length = L

length= L feet

let Width= W

from the question,

twice the width = 2W

then L = 2W-19

the area of the rectangle

Area= length × width

Area= 2W-19×W

Area= 2W^2-19W

Area= W(2W-19)
