mean is 83.71%.

Step-by-step explanation:
- First of all, a 2 foot kangaroo is casting a 7 foot shadow.
- Next we do 7 divided by 2 which equals 3.5.
- Since we know the shadow is going to be 3.5x the object size we have to divide its shadow by 3.5
- 14 divided by 3.5 is 4 so the Eucalyptus tree is 4ft long
<u><em> Your answer=4ft </em></u>
