Perimeter is the distance around an object.

One side of the square is $1\frac{1}{2}$ inches.

All sides of a square are the same length.

To find the perimeter, add $1\frac{1}{2}$ inches four times, or multiply $1\frac{1}{2}$ inches by 4.

$1\frac{1}{2}$ in. + $1\frac{1}{2}$ in. + $1\frac{1}{2}$ in. + $1\frac{1}{2}$ in. = $6$ in.

The perimeter of the square is 6 inches.

Opposite sides of a rectangle are congruent.

So, the side lengths are 4 feet, 3 feet, 4 feet, and 3 feet.

The perimeter is the sum of the side lengths.

Perimeter | = | 4 ft + 4 ft | + | 3 ft + 3 ft |

| = | 2 × 4 ft | + | 2 × 3 ft |
