Answer:
The longer length is either 99, 33 or 11 inches
Step-by-step explanation:
Given

Required
The length of the longer side
Area of a rectangle is:

List out all possible products that give 99 [Assume the dimension are whole numbers]



List out the longer factors

<em>Hence, the longer length is either 99, 33 or 11 inches</em>
1. Use the Pythagoras theorem
13^2 = x^2 + 5^2
solve for x and youll get the height of the roof.
2. let x = length of the rpoe)-
x^2 = 9^2 + 12^2
3. Pythagoras again
20^2 = x^2 + 12^2
ABC and DBC is Side Angle Side
