24.5
H=4. Solving the equation gives you two answers, 4 and -0.5 and since you can't logically have negative height, 4 is the only legitimate answer that is realistic.
This is the diffiarence of two perfect squares. this should be memorised, but if not here it is
a^2-b^2=(a-b)(a+b)
so 16^2-81=16^2-9^2
so the answer is (16-9)(16+9)
