Answer:
203
Step-by-step explanation:
When calculating surface area, you add the area of each side.
Base: LxW = 7x7 = 49
Triangle Sides: 1/2 b x h = 1/2(7) x 11 = 38.5
4 sides: 38.5x4 = 154
154+49 = 203

Answer:
20-gon
Step-by-step explanation:
First we start with the formula to find what the sum of angles will be if we know the number of sides.
S=(n-2)*180 where S is the sum of angles and n is the number of sides.
Normally you'd plug in n to find S, but you can do the opposite too.
3240=(n-2)*180
Let me know if you need help working it from here.
