Answer:
Area of a rectangle = 42 square units
Step-by-step 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
