QuestionA trapezoidal trough has a top width of 15 ft and a bottom width of 9 ft and a depth of 6 ft . The area of the cross section of the channel is $\square$ square feet.

Studdy Solution
Calculate the area:
$$A = \frac{1}{2} \times 24 \text{ ft} \times 6 \text{ ft}$$ $$A = \frac{1}{2} \times 144 \text{ ft}^2$$ $$A = 72 \text{ ft}^2$$
The area of the cross-section of the channel is:
$$\boxed{72 \text{ ft}^2}$$
