Question 478748
The side of the pool and grass  = {{{sqrt(196)}}},  = 14 m.
The length of the grass is given as 3 m, so the pool length will be 11 m.

The area of the grass is total area, 196 m sq, minus the area of the pool, 11^2, which is 121 m sq.
This results in the area of the grass being 75 sq. m.
