Help me please? maybe? I hate math. and if it's not too much trouble, my teacher didn't give us the equation for this kind of stuff.

The end answer is 40.75cm^2 (squared)

How i got there was i used the equation

1/2 (a×b ) + 3/2 (b×s)

where A is the height of the base triangle

Where b is the side length (it does not matter which one but it is one of the 5's)

The second b stands for the same thing.

Where S represents the height of the pyramid.

So then we get this:

1/2 (4.3 × 5) + 3/2 (5 × 4)

you solve the parentheses first and so on and so on.

I hope this helps :p
