split it up (make in to net and unfold or something)
2 triangles (identical)
2 side rectangles (identical
1 base
area of rectangle=lh or wl etc
area of triangle=1/2bh
triangles
b=16
h=6
area of triangle=1/2*16*6=48
times 2 since 2 of them
48*2=96
2 side rectangles
10 by 7
10*7=70
times 2 since 2 of them
70*2=140
base
16by 7
16*7=112
add them
96+140+112=348
answer is C
