A = 1/2 bh
A = 1/2 (21)(8)
A = 1/2 (168)
A = 84
When you see the fraction 33/16, you realize that 33 divided by 16 is 2 remainder 1, so you add the 2 to the original 6, then put the remainder 1 on top of 16 ,which gives you 8 1/16
If the box if cubed for volume then lbh is 25x25x100=62500 cm ^3...if that's right. hope it helps any.
On desmos, a graphing calculator, I inputted your numbers, and I got that each side is 11 units long. Therefore, because a hexagon has 6 sides, you would have 6 * 11 = 66 units.
Therefore, your answer is 66.
Hope this helps and have a nice day:)
all you have to do is see whether both variables of each point meet both contraints:
for a) 1<3 and 2>1 is true so a is a solution to the system
