A garden has four sides that are all the same length. Each side measures x + 5 units. The garden's perimeter is 144 units. What is the value of x?

31

Step-by-step explanation:

Each side=L=x+5

Since the garden has four equal sides, it seems to look like a square.

So perimeter of square=4L

So

4L=144

4 (x+5) = 144

4x+20=144

4x=144-20

4x=124

x=31 (dividing both sides by 4)
