Learning Target:Students will learn how to use the

perimeter and area formulas to find the perimeter and area of rectangle

figures.

What is the difference between finding the perimeter of a figure and the area

of a figure?

What is the difference between finding the perimeter of a figure and the area

of a figure?

Perimeter: the distance around the figure.

Formula for a Rectangle: Perimeter = 2 times the length plus 2

times the widthp = 2L + 2w

(Don’t forget PEMDAS.)

Label: feet, meters, inches, etc.

Area: the amount of surface the figure covers.

Formula for a Rectangle: Area = length times width

A = Lw

Label: square feet (ft2), etc.

Find the perimeter and area of the rectangle with the given dimensions.

Length = 9 m, width = 5 m

Length = 50 ft, width = 22 ft

Find the perimeter and area of the rectangle with the given dimensions.

Length = 9 m, width = 5 mp = 28 m, A = 45 m2

Length = 50 ft, width = 22 ftp = 144 ft, A = 1,100 ft2

Use the given information to find the missing length.

Area of a rectangle = 91 in2 , width = 7 in, length = ?

Perimeter of square = 132 cm, side length = ?

Use the given information to find the missing length.

Area of a rectangle = 91 in2 , width = 7 in, length = 13 in

Perimeter of square = 132 cm, side length = 33 cm

How would be finding the perimeter and area of a square be different then

a rectangle?

Formula for a Square:

Perimeter = 4 times the side lengthP = 4s

Area = (side lengths)2

A = s2

Find the perimeter and area of a softball diamond which is 60 ft by 60 ft.

Find the perimeter and area of a softball diamond which is 60 ft by 60 ft.

P = 240 ft

A = 3,600 ft2

Tell whether you would use perimeter or area to help you decide how much

of the item to buy.

Can you use the perimeter and area formulas to find the perimeter and

area of rectangle figures?
