Answer:
1. 96
2. x= 10.909 (10.91 (rounded))
Explanation:
1. You can break the figure into 3 parts, a triangle and 2 rectangles
For the triangle, we have this information:
height is 3
length is 8
angle is 90 (right angle)
area = 0.5 * 3 * 8 * sin(90)
area is 12
For the two rectangles, just multiply the length * width
5 * 4= 20
8 * 8= 64
Then add them ALL together
12 + 20 + 64 = 96
2. x = √(12^2 - 52^2)
x= 10.09
(10.91(rounded))
