Question

The length of a rectangle is 2x – 3 feet, and the width is 5 feet. What is the area of the rectangle in square feet?

A. 7x – 15
B. 10x – 15
C. 10x – 8
D. 7x – 8

Answer 1

5(2x - 3)

5 * 2x = 10x
5 * -3 = - 15

10x - 15

Answer 2

The area of a rectangle is the product of its length and its width. It is expressed as:

Area = l x w

We use this equation, to solve this problem.

Area = l x w
Area = (2x – 3) x 5
Area = 10x - 15

Therefore, the correct answer is option B.
