Answer:
40.81125m²
Explanation:
Hello!
Step 1: Rectangle
We can find the area of the rectangle by multiplying the base by the height.
- A = base * height
- A = 5m * 2m
- A = 10m²
Step 2: Area small semicircles
If we add the two semicircles, we can see that it's actually 1 whole circle.
So we can simply find the area of the whole circle.
radius = 1/2 * diameter
- A = πr²
- A = (3.14)(1m)²
- A = 3.14m²
Step 3: Large semicircle
Now for the last part, the large semi-circle at the top.
Since it's half a circle, we can manipulate the formula by finding half of it.
- A = (1/2)πr²
- A = (1/2)(3.14)(2.5m)²
- A = (1/2)19.625m²
- A = 9.8125
Step 4: Total Area
Total area = 10m² + 3.14m² + 9.8125m²
= 40.81125m²
