Let’s find the perimeter of this surface if each square is equal to one foot.

Count the number of sides.

Perimeter = 24 feet

slide9
Try this one!

Count the number of sides to determine the perimeter of this flat object.

The perimeter is equal to 12.

Family A

Family B

Let’s do these problems together.

Two neighbors build swimming pools. This is what the pools look like.

Which family has the pool with the bigger swimming area?

slide11
Family A

Family B

The area of Family A’s pool is?

8 square units.

The area of Family B’s pool is?

7 square units

Therefore, Family A has the pool with

the bigger swimming area.

slide12
Family A

Family B

Now look at those same two pools. Which family has more side panels of the pool to clean?

The perimeter of Family A’s pool is 12 units long.

The perimeter of Family B’s pool is 14 units long.

Therefore, Family B has more side panels of the pool to clean.
