1. 96

2. x= 10.909 (10.91 (rounded))

Step-by-step 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))

answer: 8 years

step-by-step explanation:

the explanation is that in 8 years the child will be 20 and in 8 years the father will be 40 and 20 is half of 40.
