Answer:
7.5 units^2
Step-by-step explanation:
So, let's just break apart this trapezoid into easier shapes to work with.
We can make a 1x3 rectangle with the squares that are fully covered in.
Then, make a triangle with the squares that are partially covered in above and another triangle for those below.
Now, calculating time.
With the rectangle, do Length * Width, so 1 * 3 = 3.
With the upper triangle, do (Base * Height) / 2, so (3 * 2) / 2 = 3
With the lower triangle, do (Base * Height) / 2 as well, so (3 * 1) / 2 = 1.5
Add these all up and you get 7.5 units^2
Hope that helps.
