Answer: 1,486 square meters
Step-by-step explanation:
First, you need to figure out the area of the triangle using the formula 1/2bh.
1/2 (60)(60) = 1800
Next, you need to find the area of the circle using the formula πr². The question instructs you to use 3.14 in place of π. The diameter is 20, meaning the radius is 10.
(3.14)(10)² = 314.16
Now all you have to do is subtract the two values because you are trying to find the shaded region within the triangle.
1800 - 314.16 = approximately 1,486
