Let's make group of 3 numbers
1+2-3=0
4+5-6=3
7+8-9=6
...
97+98-99=96
s=1+2-3+....+97+98-99=0+3+6+..+96=3*(0+1+2+3+...+32)
=3*(32+0)*33/2

Answer:
8.66 ft
Step-by-step explanation:
A square is a shape that has an equivalent length and breadth across it’s cross section.
What this means is that measuring the length across the top and bottom will yield the same length value.
Thus, mathematically, let’s call the measured height h
The square of this height gives the area
thus;
h^2 = 75
h = √75
h = 8.660254037844
This is approximately 8.7 to one decimal place
The answer is 642
