Question

The length of a rectangle is 1 less than twice the width. Write the equation that could represent the area of the rectangle in terms of the width

Answer 1

Answer:

(W2-1)xW

Step-by-step explanation:

The beginning of the equation represents the length as the question states it is one less than twice the width. Because you need to multiply width and length to get area, you place the length equation and parentheses and multiply the answer to the equation by the width :) Hope this helps!

Answer 2

Based on the problem statement, we have a word problem before us, that is solving for the area of a rectangle with given sides.

Area =  2y^2-y

Given data

Let the Length of the rectangle be x

and let the width be y

From the statement "The length of a rectangle is 1 less than twice the width"

the length can we re-written as

x = 2y-1

We know that the area of a rectangle is

Area = Length*Width

Area = (2y-1 )* y

Area = 2y^2-y

hence the expression for the area is given as 2y^2-y
