• Ok so first for the rectangle:
Use the formula: b•h
50 • 20 = 1000 ft2
• Next, the triangle:
Formula: b•h/2
Add the 10 and 50, which is 60.
60 • 20 = 1200
1200/2 = 600 ft2
• For the circle:
Formula: π • r^2
The radius is 10ft
3.14 • 10^2
3.14 • 100 = 314 (Whole circle)
Since we need half of the circle, we divide by 2 to split them.
314/2 = 157 ft2
• Now add all together:
1000 + 600 + 157 = 1757 ft2
