Let x be the number of additional feet added to the length. Then the new area is 119 square feet:

7%2812%2Bx%29=119

Solve using basic algebra....

Or get some good mental exercise and solve the problem informally:
7 times what new length makes the new area 119 square feet? Then find the difference between the new length and the current length....
