Question

Theresa created a piece of art by attaching a square plank to a triangular plank. The square plank has a perimeter of 48 inches. The triangular plank has a base length of 12 inches and a height of 6 inches. She wants to cover the piece of art with colored paper.

How many square inches of paper are needed to cover Theresa's art piece?

Answer 1

180

Explanation:

The perimeter of the square is 48. The Square has 4 sides so 48/4 = 12.

One side of the square is 12. Use
`12^(4)` to calculate the area.
`12^(4)` = 144.

Triangle base = 12 and height = 6. 12 times 6 divided by 2 = 36.

144 + 36 = 180
