The area of a rectangle is length times width or l*w or lw
so the length being 22 cm and width 14 cm
22*14 = 308 cm
the area of the dance floor is 308 square cm of the scale drawing...
it says that 5cm in the scale drawing is 8 ft in reality...
so 35.2 ft and 22.4 ft are the new length and width respectively
so 35.2 times 22.4 is the actual floor area
788.48 ft
Hope this helps ;)

0.00592 ≈ 0.0059 to 4 decimal places.
The number after the fourth decimal place is 2, and this is not up to 5, so we round down.
Dy/dx h = 32t - 16t^2
v = 32 - 32t
at Max hight speed is 0m/s
therefore
0 = 32 - 32t
t = 32/32 = 1 s
so it goes up to Max hieght in 1 s
and it takes another 1s to come back
thus time after launch to return to ground is 2s!
