The emphasis is on the rectangular bottom of the pool. Depth is not relevant.
w for width, L for length.
wL is the area, so wL=570 square meters.
Perimeter is 2w%2B2L=98 meters.
Two equations in two unknown variables. Solve for one variable and substitute into the other equation and get the value for one variable...

as a start,
w=570%2FL;
2w%2B2L=98
2%28570%2FL%29%2B2L=98
2%2A570%2B2L%5E2=98L
.
