Hello!
The formula for the perimeter of a rectangle is: P = 2(l + w). In this formula, P is the perimeter, l is the length, and w is the width.
Suppose the length of the rectangle is 11 meters. We can substitute that value into our formula and solve for the missing side.
32 = 2(11 + w) (use the distributive property)
32 = 22 + 2w (subtract 22 from both sides)
10 = 2w (divide both sides by 2)
w = 5
Therefore, the length of the missing side is 5 meters.
