15(30)(2) + 24(30)  ??  if I read the picture right..

30(30 + 24)

30(54) = 1620 ft^2

are the front triangle and rear triangle covered as well?

amistre64 · Answer

herons formula;  s= perimeter/2

sqrt(s(s-15)(s-15)(s-24))

to amistre64: yes

anonymous · Answer

(12*9)*2 triangles
+ (30*15)*2 sides
+24*30 ground
=1386

amistre64 · Answer

or since the height is 9;   9(24) will give both areas...
