Answer: 170 square units
Step-by-step explanation:
So, what we need to do is to separate that triangle at the too from the rectangle.
Now we have two shapes.
Lets find the are of the triangle:
The height of the triangle is 7, which is perpendicular to the base.
The base is going to be also 20 because its the same length as the rectangle’s.
The formula for the are of a rectangle is
1/2 x Base x height (1/2 x 20 x 7) which is equal to 70 square units.
The area of the triangle is 100 square units (20 x 5)
We add the area of the shapes:
100 square units + 70 square units= 170 square units
