Find the area of the figure below

ft squared

Step-by-step explanation:

This figure is just made up of two semicircles, which add up to one circle, and 1 rectangle.

The rectangle area is easy; it's just length times width: 15 * 25 = 375.

Now, for the two semicircles. Since they just add up to 1 circle, we can find the area of a circle with radius (15/2). The area of a circle is: , where r is the radius. So: A = .

Finally, we add these two areas together: + 375.

Thus, the answer is ft squared.
