Multiply @zoejay1

anonymous · Answer

it is a triangle so you will need to divide the answer in half, to get the answer you need to do B xH divided by 2

anonymous · Answer

yes! you multiply

anonymous · Answer

30 * 30 = 90 + A*C/2 = 270 it equals 360 ft.

anonymous · Answer

alright, what is the base of the porch, the bottom of thr triangle

anonymous · Answer

but that's not an answer choice @CC-Right :(

calculusxy · Answer

Area of a triangle = $$\frac{ 1 }{ 2 }(b \times h)$$
We also know that all the sides of a square are congruent with each other.
