Answer: 30 ft tall
Step-by-step explanation: X= the height of the tree in feet
27/x = 4.5/5
(4.5)(x) = (27)(5)
(4.5)(x) = 135
divide by 4.5 to isolate x
135/4.5 = 30
x = 30
the tree is 30 ft tall
The first condition is for the perimeter of the equation so:

Now the secon condition is that the sum of two sides should be:

so the negative option and 0 don't make sence dor a distance, then we try with the value of b=0.5
So in the first equation will be:

So the condition:

this is false, so the solution is
