Question

a rectangle has a width of 3 and a length of 4. find 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: Substitute the given values into the formula

We know that the length is \( 4 \) and the width is \( 3 \). Substituting these values into the formula, we get \( A = 4\times3 \).

Step3: Calculate the product

\( 4\times3 = 12 \).

Answer:

12
