Answer:

13 square units

Step-by-step explanation:

The bounding rectangle is 4 units wide and 5 units high, so has an area of 4×5 = 20 square units. From that are subtracted the areas of 4 triangles. 2 of them are 3 wide and 1 high, so have a combined area of 3×1 = 3 square units. The other two are 1 wide and 4 high, so have a combined area of 1×4 = 4 square units.

Then the area of the parallelogram is ...

20 -3 -4 = 13 . . . . square units

lukranit [14]

The formula for the area of a trapezoid is
A = (1/2)(b₁ +b₂)h

Substitute the given information and evaluate. (Make sure all dimensions have the same units.)
A = (1/2)(12 ft +5 ft)(8 ft)
A = 68 ft²

The area of the trapezoid is 68 square feet.
