Question

PLEASE HELP I WILL MARK BRAINLIEST! Can someone help me do the surface area of this?​

Answer 1

Answer:

412 FT^2

Step-by-step explanation:

The formula for a triangle is A=1/2bh

The front and back are 36 ft - 9x8=72/2=36

Make sure to do that x2 because it counts for BOTH front and back.

The bottom rectangle is 136 ft since 17x8=136.

Now the sides, 1/2 of 17x6 = 102. Do that for both sides.

Add: 36x2 + 136 + 102x2

36x2=72

102x2=204

-------------

72+136+204= 412

Thus, the answer is 412 ft^2

Answer 2

Step-by-step explanation:

area of the front (8ft×9ft)/2=36ft²

the back is similar to the front so the back is also (8ft×9ft)/2=36ft²

area of the right 17ft×6ft=102ft²

the left is similar to the right so the left is also 17ft×6ft=102ft²

area of the bottom 8ft×17ft=136ft²

Area total =36ft²+36ft²+102ft²+102ft²+136ft²

area total =412ft²
