The area of a square is Side x Side. Since its sides are equal you have:
S*S = 1.69
S^2 = 1.69
S = √(1.69)
S= 1.3 km

Answer:
volume of box = l*b*h
= 8/9*5/12*3/10
= 1/9 cubic feet
Step-by-step explanation:
The time of takeoff of this hovercraft would be 0 seconds, as if you were starting a timer. So, if you plug in 0 for x (unit for seconds) in your equation, it will look like this:
h(0) = -3(0 - 3)² + 108
Parenthesis first
h(0) = -3(-3)² + 108
Exponents next
h(0) = -3(9) + 108
Multiplication
h(0) = -27 + 108
Combine like terms
h(0) = 81: The height of the hovercraft at the time of takeoff is 81 meters!
Hope this helps :)
