Answer:
160 cm²
Step-by-step explanation:
Hello!
We can find the area of the blue shaded. region by finding the area of the rectangle, and subtracting the area of the triangle.
Area of rectangle:
Find the area of the rectangle
- A = Base x Height
- A = 10 x 20
- A = 200
The units are cm so the area is 200 cm²
Area Triangle:
Find the area of the triangle
- A = 0.5( Base x Height)
- A = 0.5(10 * 8)
- A = 0.5(80)
- A = 40
The units are cm so our area is 40 cm²
Area Shaded:
Now we can simply subtract the triangle area from the rectangle.
