we have
2 triangles
1 base
2 roof rectangles
4 sides

are rectangle=lw
area triangle=1/2bh

triangles is 1/2 times base times height
triangle=1/2 times 17 times 7
but wait, there are 2 triangles
1/2 times 2 times 17 times 7=119

now roof tiles
14*11+11*11=154+121=275

sides
2(10*17+10*11)=2(170+110)=2(280)=560

bottom
17*11=187


add them all up
119+275+560+187=1141

answer is 1141 in^2
