Answer:
95 square units
Step-by-step explanation:
Surface area of pyramid = 4(side area) + base
Solve for the base first.
Area of base = s*s = 5*5 = 25
Next solve for one of the sides.
Area of triangle = 1/2 b*h = 1/2 5*7 = 17.5
Plug these back into our original equation.
Surface area of pyramid = 4(side area) + base
Surface area of pyramid = 4(17.5) + 25
Surface area of pyramid = 70 + 25 = 95 square units
Simply subtract 8.72 from 20.08 and you get the answer which is 11.36$
The answer is 6 1/4, because if you making 1/2 = 2/4, 2 + 3 = 5, the 4 stays the same, so its 5 5/4, and to make it proper, you make it 6 1/4
