Check the picture below.
the distance from 1,2 to 1,8 is simply 6 units, we can read that off the grid. Now let's see what the other distances are, and add them all up to get the perimeter.

A. Yes answer it’s function correct.
Answer:
surface area of the square pyramid
=(32×32)+(2×32×20)
=1024+1280
=2304 square feet
Answer:
What do u need the help for?
Step-by-step explanation:
The answer is -4.4, -2 1/2, -.5, 1/2, 1.5, 3.8
Explanation:
If we converted all the numbers to decimals it would look like this:
1.5 = 1.5
1/2 = .5
-2 1/5 = -2.5
-.5= -.5
3.8 = 3.8
-4.4 = -4.4
Then you would just arrange them from least to greatest starting with -4.4 and ending with 3.8.
Hope this helps!
