Answer:

12 ft 9 5/6 inches

Explanation:

We can use proportions to solve this. Put the height of the object over the shadow. Change the height of the object to inches

Alonzo

5 ft 11 inches = 5 ft *12 inches/ft + 11 inches = 60 inches + 11 inches = 71 inches

2 ft shadow = 2* 12 inches/ ft = 24 inches

Basketball goal

4 ft 4 inches = 4 ft *12 inches/ft + 4 inches = 48inches + 4 inches = 52 inches

Alonzo Basketball

71 inches x inches tall

------------ = --------------------

24 inches 52 inches

Using cross products

71*52 = 24*x

Divide each side by 24

71*52/24 = 24x/24

923/6 =x

Lets change this to a mixed number

6 goes into 923 153 times with 5 left over

153 5/6 inches

Now we need to change inches to feet

How many time does 12 go into 153 12 times (12*12 =144 with 9 left over)

12 ft 9 5/6 inches
