I can't picture the deck. Top? Bottom?
All I can say is that 24 = 28-4, the difference between top and bottom.
But the 7^2+24^2=25^2 seems to be for the legs and diagonal of a triangle. Oh, well, maybe you have a diagram in front of you.
New tile is being laid on a floor that is 12 ft. long and 9 ft. wide. Each square tile measures 9 inches on each side. How many tiles will be needed?
Ans. 192
Please tell me how they got 192
Thank you.
PS digressing
how do I sent you diagrams, i.g., triangle diagram of a deck?
