Answer:

X=8

Explanation:

Given that the Area is 36ft^2, and the formula for calculating the area of a triange is:


a_(t) =h_(b)b/2

we have:


36 = ((x+1)*x)/(2)

we can start solving for x through the quadratic formula, but that will take long.

Instead, we can try replacing x by some numbers.


36*2=(x+1)*x


72=(x+1)*x

After a while,


72=(8+1)8\\\\72=9*8\\\\72=72.

We find that x=8.

IMPORTANT: X can also be -9 in this case. But a negative measurement doesn't make sense in this context, I would say that x=8 in this problem.
