Kinda ned some how do i solve this problem

So we know that the area of only the pool is 198 ft^2. To find the area of the entire yard, multiply length times width so:

Area of yard = 22 ft  x  30 ft 
Area of yard = 660 ft^2

Now subtract the pool area from the yard area:

660 - 198 = 462

So the area of only the yard is 462 ft^2

Hope this helps!!
