A swimming pool is 19 feet wide and has transverse cross-sections which look like the picture above. If the pool is being filled at a rate of 0.7 cubic feet per minute, how fast is the water level rising when the depth of water is 3 feet?

I know the Volume of the pool when h is less than 7 so I was able to get the related rates part. But I still need to find the volume of the pool when h is greater than 7. Please Help!
