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
Hello!
I dont a graph to show you but I will solve the answer.
12.7 + 5.3 <span>≥ s
18 </span><span>≥ s
s </span><span>≤ 18
</span><span>That is your answer.
Enjoy.
