Step-by-step explanation:
Step 1: Set up the formula for the surface area of a regular pyramid.
SA =
where :
- SA equals the total surface area of the pyramid,
- p equals the perimeter of the base,
- h equals the slant height of the pyramid
- B equals the area of the base.
Step 2: Plug the perimeter of the base into the formula
you can calculate the perimeter by multiplying the length of one edge by the number of edges.
Step 3: plug the value of the slant height into the formula (it is not the perpendicular height)
Step 4: find the area of the base (depend on the shape of the base)
Hope it will find you well.
Answer:
24
Step-by-step explanation:
Because you multiply the base x the height to get the are of a figure
12: 12,24,36,48,60 etc.
2:2,4,6,8,10 etc.
If the angles are below 90 degrees this would make this triangle an acute triangle
