Hi Mitsu there is no fraction to this. You multiply the base and height to get the area. So 512 x 512 = 262144
The time taken to get to the 4th can be obtained by dividing the distance given by the speed of the lift.
Distance, height from ground to 4th floor = 42 feets
Time taken to get to the 4th floor = t
Recall :
Time = Distance / speed
- We aren't given the speed of the lift ;
- Assume speed of lift is 7 ft/sec
The time taken to get to the 4th floor will be :
Therefore, to obtain the time taken, divide the distance or height of the 4th floor by the speed of the lift.

It should be A= 1/2bh but im not sure why you wrote those extra things. Are we supposed to use them?
Don't you just add, though?
3.8 + 5.25 = 9.05 hours?
