Nick and lisa are building a square pond in their backyard. They wish to put a 2 foot wide brick border around the outside. If the total area of the border and the pond is 196 square feet, find the length of the side of the pond.

the length of the pond is 10 feet.

Step-by-step explanation:

The computation of the length of the pond side is shown below:

Let us assume the length of the pond side be x feet

Now the one side length with the brick border is x + 4

And, the pond is 196 square feet

Now the equation would be

(x + 4)^2 = 196

(x+4) = 14

x = 10

Therefore, the length of the pond is 10 feet.
