Question 1160939: Hi,
I need help with this question please.
A swimming pool is 45m long and 9m wide. The perpendicular depth at the deep end is 4m and at the shallow end is 1.2m, the slope from one end to the other being uniform. The inside of the pool needs two coats of a protective paint before it is filled with water. Determine how many litres of paint will be needed if 1 litre covers 15m².
Thanks

There is no such a notion/conception as a "perpendicular depth".


There is a notion/conception "depth", instead, as one single word.


Its meaning is the distance from the calm water surface to the bottom, measured vertically down.
