Question

If a 40 foot tree cast a 12 foot shadow find the length of the shadow cast by a 27 foot tree

Answer 1

8.1 ft

Explanation:

We can use proportions to solve. Put the height over the shadow

40 ft 27 ft

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

12 ft x ft

Using cross products

40x = 12*27

40x =324

Divide each side by 40

40x/40 = 327/40

x = 8.1

The shadow is 8.1 ft
