Hi, hope this helps. I saw the comments discussing about the reason of the side of base to be 20cm. I look into the question and confirm that the base and height in this question are variables. The question intends to get you try to draw one (any possible one) to scale and measure to calculate the surface area I believe.

Another obvious combination would be swapping the value of b and h in my solution, as it still satisfies the 24^2 + 10^2= 26^2, then the area of square base be 48x48 , area of triangle 0.5x48x10, total surface area 3264cm^2
TQ sir
