Answer:
9 inches
Step-by-step explanation:
4 x 3 = 12
so 3 x 3 = 9
A=LW,
W=L/2, L=2W so:
A=(2W)W
A=2W^2 and A=34 so:
2W^2=34
W^2=17
W=√17, and since L=2W
L=2√17
So the length is 2√17 and the width is √17
(length≈8.25 and width≈4.12 if you wanted approximations...)
If there are 8 groups of 65 students, that means they can seat 8*65 students total. 520 students
So, first we input 6
24 - 6 = 18
So we now need to find the square root of 18
If you're allowed to use a calculator, the square root is 4.242
But if you don't, let's get as close as we can:
√(9 * 2)
Because the square root of 9 is 3:
3 * √2
