Bethany added a decorative border across the top of each wall of her kitchen. a diagram of her kitchen is shown below.

she used a total of 62 feet of border. what is the length in feet of the unlabeled wall?
choices:
a.) 5
b.) 10
c.) 8
d.) 13

For this case we have that the perimeter of the figure is given by the sum of its sides, they tell us that the perimeter is 62 feet.

So:

Let "x" be the variable that represents the length of the unlabeled wall, so the perimeter is:

We find the value of "x":

Thus, the length of the unlabeled wall is 10 feet.
