She needs 11 yards + 11 yards + 19 yards + 19 yards = 60 yards. She already has 8 yards so she needs 52 more.

52 yards,
Add 19 + 19 + 11+11 equals 60 yards. Take away 8 yards leaving 52

The total amount of fencing she needs is the perimeter in other words the width multiplied by two plus the length multiplied by two. When you get the perimeter you subtract the 8 yards left over from last year and you have the answer. She needs to buy 52 more yards.

52 yards
11+11+19+19 = 60 <---which is much she will use and since she has 8 yards from last year, you subtract 60-8 which will give you 52 yards

i think you make a right triangle out of 19 and 11, and then the third side will be x-8
give it a shot
