Question

A rectangle has sides measuring (4x + 5) units and (3x + 10) units.

Part A: What is the expression that represents the area of the rectangle?
a) (4x + 5)(3x + 10)
b) 4x + 3x + 5 + 10
c) 4x^2 + 15x + 50
d) 4x^2 + 3x + 5x + 10

Answer 1

The expression that represents the area of the rectangle is (4x + 5)(3x + 10) (Option a).

Step-by-step explanation:

The expression that represents the area of the rectangle is (4x + 5)(3x + 10) (Option a).

To find the area of a rectangle, we multiply the length by the width. In this case, we have (4x + 5) as the length and (3x + 10) as the width. Therefore, the area is (4x + 5)(3x + 10).
