Benin is sawing board to make a deck. What is the area of the deck?

C. 108.5 square feet

Step-by-step explanation:

Area of a rectangle: length x width

Area of a triangle: (base x height)/2

First find the rectangle's area:

10ft x 7 ft

70ft^2

Find the right side triangle's area:

(7ft x 5ft)/2

35ft^2/2

17.5ft^2

Now find the left side triangle's area:

There is no base number included, but the other triangle has a base of 7ft. Considering the triangle is attached to a rectangle's side, we can conclude this triangle will have the same base because a rectangle's parallel side will always equal each other

(7ft x 6ft)/2

42ft^2/2

21ft^2

Finally, add all of these areas together

70ft^2 + 17.5ft^2 + 21ft^2

87.5ft^2 + 21ft^2

108.5ft^2
