Answer: 66 sq ft
Step-by-step explanation:
Break up the shape into three separate shapes
8 * 3 = 24 for the rectangle
There are 2 triangles
The formula for the area of a triangle is 1/2(b)(h)
1 of the triangles has a base of 4 and height of 12
1/2(4)(12) = 24
The other triangle has a base of 3 and height of 12
1/2(3)(12) = 18
24 + 24+ 18 = 66
Hello!
to find the percent of a whole, use this equation here:
(remaining) / (total) = X
X * 100 = %
in this case:
12 / 15 = 0.8
0.8 * 100 = 80
your answer is 80%
I hope this helps, and have a nice day!
