Leave us a comment of this math problem and its solution (i.e. if it is still somewhat unclear...): Steve
No, your solution starts with h=25cm, but the question says that h=24cm.

So, looking at one-half of the isosceles triangle, x2 + 242 = (32-x)2    solves to x=7cm,   which gives the area of the isosceles triangle as 7x24 = 168cm2 Dr Math
thank you, we corrected 25 to 24 as altitude.... #### Following knowledge from mathematics are needed to solve this word math problem:
