Gary's garden is shaped like a rectangle with two pairs of sides of equal length and it has a perimeter of 28 feet explain how to find the length of the other sides if one side measures 10 feet

If you draw out a rectangle, two opposite sides will be 10 feet and the other two sides we will label as x.

The perimeter of a rectangle is adding up all the sides, so if you add up all those sides you get

x + x + 10 + 10

we know the perimeter is 28 feet, so we know

x + x + 10 + 10 = 28

now we can solve for x

x + x + 10 + 10 = 28

2x + 20 = 28

2x = 8

x = 4

one of the other sides is 4 feet
