Area of semi-circle: 100.53 square meters

Area of triangle: 60 square meters

Total area: 160.53 square meters

Step-by-step explanation:

Area of semi-circle:

To find the area of a semi-circle, you have to find the area of the circle, then divide by 2.

The area of a circle is determined by the formula

Here, we know that the diameter of the circle is 16m, so the radius (half the diameter) will be 8m.

Now divide the area in half, and get 100.5309...

The question asks you to round to the nearest hundreth, so your answer will be 100.53

Area of triangle:

The formula for the area of a triangle is

Here, we have a base of 8m, but we don't know the height.

However, we do know the length of the other legs, so using the pythagorean theorem, , we can insert 8 for a, and 17 for c, giving us the equation

We now know the height is 15m, so if we plug this into our first equation, we get , which is equal to 60

Total area:

To find the total area, we just have to add the area of the triangle to the area of the semi-circle
