## Area of Squares and Rectangles

#### 1. What is the perimeter of a rectangle of sides 4 cm by 3 cm?

Perimeter of rectangle

= 4 cm + 3 cm + 4 cm + 3 cm

= 14 cm

The perimeter of the rectangle is 14 cm.

= 4 cm + 3 cm + 4 cm + 3 cm

= 14 cm

The perimeter of the rectangle is 14 cm.

The perimeter of a rectangle is the total distance around it.

#### 2. What is the perimeter of a square of side 4 cm?

Perimeter of square

= 4 cm + 4 cm + 4 cm + 4 cm

= 16 cm

The perimeter of the square is 16 cm.

= 4 cm + 4 cm + 4 cm + 4 cm

= 16 cm

The perimeter of the square is 16 cm.

The perimeter of a square is the total distance around it.

#### 3. Find the perimeter of each figure below.

What can you tell about their perimeter?

The perimeter of a figure is the total distance around it.

= 1 cm + 1 cm + 1 cm + 4 cm + 2 cm + 3 cm

= 12 cm

= 2 cm + 1 cm + 1 cm + 2 cm + 1 cm + 1 cm + 1 cm + 1 cm + 1 cm + 1 cm

= 12 cm

The perimeter of each figure is 12 cm.

Two different figures can have the same perimeter.

**Perimeter of figure A**= 1 cm + 1 cm + 1 cm + 4 cm + 2 cm + 3 cm

= 12 cm

**Perimeter of figure B**= 2 cm + 1 cm + 1 cm + 2 cm + 1 cm + 1 cm + 1 cm + 1 cm + 1 cm + 1 cm

= 12 cm

The perimeter of each figure is 12 cm.

Two different figures can have the same perimeter.
