Four triangles, five boxes. Find the area of all, that might help.

jim_thompson5910 · Answer

the octagon can be divided up into 8 congruent triangles which have the same area

the height of each triangle is 30/2 = 15 inches, the base of each triangle is 12.43 inches

jim_thompson5910 · Answer

so if you can find the area of this triangle

|dw:1362459209907:dw|

then all you have to do is multiply that result by 8 to get your final answer
