So you have two shapes. Do you see those two shapes?

anonymous · Answer

@FortyTheRapper yes

fortytherapper · Answer

So we need to find the formula for each of those shapes (The area of a rectangle and the area of a half-circle, since those are our shapes)

anonymous · Answer

@FortyTheRapper i don't really understand

fortytherapper · Answer

The area of a half circle is $$\frac{ \pi r^2 }{ 2 }$$
The area for a rectangle is length times width

Let's do one at a time. If the length of the rectangle is 26 and the width is 12, how would we find the area?

anonymous · Answer

@FortyTheRapper times? 26x12?

fortytherapper · Answer

Yep, calculating that will find one part of the area
