You would use the function root(Xsub2-Xsub1)^2+(Ysub2-Ysub1)^2.
Now plug in your numbers.
This gives you root(7-1)^2+(5-(-3))^2.
Simplify to root(6)^2+(8)^2. Simplify again to root36+64.
Simplify one more time to root 100. now solve.
Your answer is 10.
2. He can break his strand of 10 blocks into 3 3 times 4. I think it is 74 blocks are needed.
8, 17/12 9, 9/24 10, 13/10 11, 11/10

Perimeter = 2L + 2W
since it’s a square, all sides are equal so
perimeter = 4s
s = 13
so multiply 13 by 4
perimeter = 13*4 = 52
