The width of a rectangle is 4 inches (in) and the area of the rectangle is 32 in2. Which of the following is the length of the rectangle?
A.
8 in
B.
28 in
C.
36 in
D.
128 in
The correct answer is:
A. 8 in
Explanation: The area of a rectangle is calculated using the formula:Area=Length×Width\text{Area} = \text{Length} \times \text{Width}Area=Length×Width
Given:
- Area = 32 in²
- Width = 4 in
To find the length:Length=AreaWidth=32 in24 in=8 in\text{Length} = \frac{\text{Area}}{\text{Width}} = \frac{32 \text{ in}^2}{4 \text{ in}} = 8 \text{ in}Length=WidthArea=4 in32 in2=8 in
Therefore, the length of the rectangle is 8 inches.
Correct answer: A
