Answer:
95 ft²
Step-by-step explanation:
Given:
regular pyramid with,
Square base of side length (s) = 5 ft
Slant height (l) = 7 ft
Required:
Surface area
Solution:
Surface area of a regular pyramid = ½*P*l + B
Where,
P = perimeter of the square base = 4(s) = 4(5) = 20 ft
l = slant height = 7 ft
B = area of base = s² = 5² = 25 ft²
Surface area = ½*20*7 + 25
= 10*7 + 25
= 70 + 25
Surface area of regular pyramid = 95 ft²

Answer: 239 m^2
Step-by-step explanation:
Find the area for parts of the shape first.
12 x 5 = 60 x 2 (2 same looking parts) = 120
17 x 7 = 119
Add together values:
120 + 119 = 239 m^2
You have to pay attention in this:
- The order doesn't matter
- No repetition
- You can not chose all available elements (just 4)
So in this case your formula must be: 9C4= 9!/(4!*(9-4)!) = 126 ways
=$75.66 all in all and $67.99 dollars
