D 8 cm

1 answer

To find the length of the rectangle, we can use the formula for the area of a rectangle, which is:

\[ \text{Area} = \text{Length} \times \text{Width} \]

Given that the area is 75 square centimeters and the width is 5 centimeters, we can plug in these values:

\[ 75 = \text{Length} \times 5 \]

To find the length, we divide both sides by 5:

\[ \text{Length} = \frac{75}{5} = 15 \text{ cm} \]

So the length of the rectangle is 15 cm.

The correct answer is:

B 15 cm
