Answer:
The answer is 840ft2
Step-by-step explanation:
for the two rectangles, use the formula: length x width
15 x 13 = 195
Since you have two rectangles on each sides, multiply by 2
45 x 2 = 390ft2
for the triangle, use the formula: base x height
2
18 x 12
2
= 108
since you have 2 triangles (one at the front, one at the back), multiply by 2
108 x = 216ft2
For the rectangle on the bottom
18 x 13 = 234ft2
Add for the TSA
234 + 390 + 216 = 840ft2
