Question

A rectangle has a length of (2c + 1) and a width of (3 + c). If c = 3, what is the area of the rectangle?

Answer 1

Area of a rectangle = 42 square units

Explanation:

Area of a rectangle = length times width.

l = (2c + 1) when c = 3, the length = 2 · 3 + 1 ; l = 6 + 1 = 7

w = (3 + c) when c = 3, the width = 3 + 3; w = 6

Area of a rectangle = length times width

Area of a rectangle = 7 · 6

Area of a rectangle = 42 square units
