area of your house be greater? Youre right! The area of your house is greater than the area of your bedroom. Lets find the area of this surface if each square is equal to one foot. Count the number of squares. 1

this surface. What is the area? The area is equal to 9 square units. Perimeter is the distance around the outside edge of a flat object. Perimeter is reported as a
total number of linear units. When you measure the amount of wallpaper border to go around a room, you measure it in lengths. Would the perimeter of your bedroom or the perimeter of your house be greater? Youre right! The
perimeter of your house is greater than the perimeter of your bedroom. Lets find the perimeter of this surface if each square is equal to one foot. Count the number of sides. Perimeter = 24 feet Try this one!
Count the number of sides to determine the perimeter of this flat object. The perimeter is equal to 12.
Lets do these problems together. Two neighbors build swimming pools. This is what the pools look Whichlike. family has the pool with the bigger swimming area? Family A Family B The area of Family As pool8 square units. is? The area of Family Bs pool is?
7 square units Therefore, Family A has the pool with the bigger swimming area. 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 long. The perimeter of Family long.
Therefore, Family B has side panels of the pool clean. As pool is 12 units Bs pool is 14 units more to Family A Family B
