The length of a rectangle is 5 ft less than twice the width, and the area of the rectangle is 52 ft squared. What is the length and width?

Hint: Draw a rectangle and define the sides to be 'L' & 'W'.

Does the problem statement define 2 relationships between L & W? What are those?

The length … is 5 … less than twice … the width …

… area … is 52 …

Hello Angie.

L = -5 + 2W

Using the area formula for a rectangle, can you write a second equation with symbols L and W and the number 52?

We can continue from there. Cheers!
