10
In this section you will learn to solve problems that involve the perimeters and areas of rectangles and parallelograms. Perimeter is the ____________________. distance around a figure The perimeter is the ____ of the lengths of the sides of the figure. sum The perimeter of the room shown here is:

11
In this section you will learn to solve problems that involve the perimeters and areas of rectangles and parallelograms. Perimeter is the ____________________. distance around a figure The perimeter is the ____ of the lengths of the sides of the figure. sum The perimeter of the room shown here is: 15 ft+ 12 ft+ 18 ft+ 6 ft + 9 ft = 66 ft

12
Some figures have special characteristics. For example, the opposite sides of a rectangle have the same length. This allows us to use a formula to find the perimeter of a rectangle. ( A formula is an equation that shows how certain quantities are related. )

14
Find the perimeter of a rectangle with a length of 17 ft and a width of 8 ft. 17 ft 8 ft

15
Find the perimeter of a rectangle with a length of 17 ft and a width of 8 ft. 17 ft 8 ft = 2(17 ft) + 2(8 ft) = 34 ft + 16 ft = 50 ft

16
Find the perimeter of a rectangle with a length of 17 ft and a width of 8 ft. 17 ft 8 ft = 2(17 ft) + 2(8 ft)= 2(17 ft + 8 ft) = 34 ft + 16 ft = 50 ft = 2(25 ft) = 50 ft
