Answer:
108 ft squared.
Step-by-step explanation:
The figure is made up of a triangle and a square.
The area of a triangle is (1/2)*b*h. The height of the triangle is 6 ft and the base is 9 ft, since the triangle shares a side with the square. Since all sides of the square are equal we know that the line that is shared by the triangle and the square must also be 9ft.
Area of the triangle: (1/2)*9*h = 27 Square feet
To find the area of a square you multiply b*h or sides squared
Area of the square: 9*9 = 81 squared feet
<em>Finally, you have to add the two areas together to get the overall area.</em>

So, 27 Feet Squared + 81 Feet Squared = 108 Feet Squared
Answer:
son = 6 mother = 48
Step-by-step explanation:
Mother = m
son = s
m = 8s
m+6 = 9/2 * (s+6)
so
2(8s + 6) = 9(s +6)
16s + 12 = 9s + 54
16s - 9s = 54 - 12
7s = 42
s = 42/7 = 6 years old
so the mother is 8s = 8*6= 48 years old
I'm guessing d b are equal and a and c are equal or I don't think we would be able to solve so going on that
if angle d is 57 angle b must also be 57
A parallelegram has angles that add up to 360
So 360= 57+57+2c
Solve
360=114+2c
-114 both sides
246=2c
÷2 both sides
123=c
