Step-by-step explanation:
Answer: 352 
Step-by-step explanation:
To find the Lateral area of a square pyramid , we will follow the three steps below:
1. Find the perimeter of the base
2. Multiply the perimeter by the slant height
3. Divide the result above by 2
That is :
The lateral surface area of a regular pyramid is lateral area = perimeter of base x slant height of pyramid) ÷ 2.
Applying the formula above:
1. The base is a square , therefore the perimeter of a square is 4L , That is
Perimeter = 4(8)
Perimeter = 32m
2. Perimeter x slant height , that is
32 x 22 = 704m
3. Dividing the result by 2 , we have :
704/2 = 352
Therefore , the Lateral area of the pyramid is 352 
Answer:
27/14
Step-by-step explanation:
you can cross multiply and simplify before you start. that way it makes it a lot easier
Answer:
2
Step-by-step explanation:
7-5=2
You just break it up, do 20x8 then another 20x8 then 5x8
