The easiest way is to write down the length of each side, and then add up
the three numbers.
In fact, that's the ONLY way to find the perimeter. If anything else needs to
be done, that's usually because you don't know all three lengths yet, and
you have to find a missing length. Once you accomplish that, you ALWAYS
find the perimeter by adding them up.
This that supposed to be a plus (+) between them or an equal (=)
This net is for a rectangular prism, we can find the surface area by adding all of the areas together.
the area of the small square is 2 x 2 = 4, there are 2 so 4 + 4 = 8
the area of one of the long rectangles is base x height. 20 x 2 = 40
there are 4 of these rectangles so 40 x 4 = 160
Adding it all together we get 160 + 8 = 168 ft^2
Answer:
Use the distance formula. Result: sqrt [ (a-c)^2 + (b-d)^2 ]
Step-by-step explanation:
distance = d = sqrt [ (a-c)^2 + (b-d)^2 ]
