The question of asking for long rectangular ponds is a pool of squares, each of which is twelve feet in length. This pool is to be made full of pools of eight feet, so that its area is equal to that of Fangchi. Q: How long is the geometry? This question means: There is a square The length of the pond is 12 feet. It is now necessary to construct a rectangular pond with a width of 8 feet. The area of the new pond should be the same as that of the square pond.
