The perimeter of the rectangle below is
118 units. Find the length of side AB

.

This a question about perimeter and equation, let's see how to solve that:

The perimeter of a rectangle is the sum of its 4 sides. In this case, we know that the perimeter is 118. We can do an equation with these datas:

We also know other informations: the side AB is equal to and de side BC is equal to 3y. In a recltangle, parallels sides have the same value. So, the side CD is equal to and the side DA is equal to 3y.

Now, we have these datas:

Let's do and solve an equation:

So, the value of y is 8. Let's replace the value of y in the side AB:

Therefore, the length of side AB is 35.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
