Answer: 59cm^2
Explanation:
We can split up the shape into a rectangle and a triangle.
Let’s find the area of both
Area of rectangle: 10 * 5 = 50cm^2
Area of triangle:
First we have to find the measures of the triangle.
To find the leg of the triangle we can simply do 10 - 4 which would give us 6.
To find the other leg, we can do 8 - 5 which is 3.
Now that we have all the sides let’s find the area.
3 * 6 * 1/2 = 9cm^2
So to find the area of the whole shape we now gotta add it up.
9 + 50 = 59cm^2
So the area of the composite shape is 59cm^2
