Answer:
156 sq in
Explanation:
If you have a rectangle measuring 13 inches by 12 inches, you will consider the side with 13 inches as the length of the rectangle and the one with 12 inches as the width of the rectangle.
The area of a rectangle is obtained by multiplying the length by the width... so, you'll get:
A = 13 in x 12 in = 156 square inches
