Find the surface area help

Answer:
Step-by-step explanation:
Just find the area for each individual shape, then add them all up.
3x8/2=12
3x8/2=12
7x3=21
3x8=24
We're actually missing a side value, and it's on the hypotenuse of the triangle shape, so we use this formula to find it.
8²+3²=c²
64+9=c
73=c
√73=8.5
8.5x7=59.5
Add them all up, and the final answer is...
128.5
