Question

1. if a rectangle is 3 inches by 5 inches, what is its area?

Explanation:

Step1: Recall the formula for the area of a rectangle

The area \( A \) of a rectangle is given by the formula \( A = \text{length} \times \text{width} \).

Step2: Identify the length and width

Here, the length is 5 inches and the width is 3 inches (or vice versa, since multiplication is commutative).

Step3: Calculate the area

Substitute the values into the formula: \( A = 5 \times 3 \).
\( 5 \times 3 = 15 \).

Answer:

The area of the rectangle is 15 square inches.
