Perimeter and Area Ms. Hernandez 4 A

Perimeter is the distance around a figure 4 ft 7 ft Perimeter formula for Rectangles Perimeter = length + width +width Perimeter = l + l Perimeter = 7 ft + 7 ft Perimeter: 22 ft + w + 4 ft

Perimeter is the distance around a figure 4 ft Perimeter formula for Squares: Perimeter = side +side Perimeter = s + s + s Perimeter = 4 ft + 4 ft Perimeter: 16 ft

Area is the number of square units needed to cover a flat surface. 4 ft 7 ft Area formula for Rectangles Perimeter = length x width Area = l x w Area = 7 ft x 4 ft Area = 28 ft^2

Area is the number of square units needed to cover a flat surface. 4 ft Area formula for Squares: Area = side x side Area = s x s Area = 4 ft x 4 ft Area: 36 ft^2

Examples Find the perimeter of the following shapes: 3 ft 6 ft 11 ft P=l+l+w+w P=11 ft + 11 ft + 3 ft P = 28 ft P=s+s+s+s P= 6 ft + 6 ft P = 24 ft

Examples Find the area of the following shapes: 3 ft 6 ft 11 ft A=lxw A= 11 ft x 3 ft A = 33 ft^2 A=sxs A = 6 ft x 6 ft A = 36 ft^2

Practice Find the perimeter of the following shapes: 6 ft 8 ft 9 ft 2 ft 10 ft 5 ft

Practice Find the area of the following shapes: 6 ft 8 ft 9 ft 2 ft 10 ft 5 ft

Practice Answers Find the perimeter of the following shapes: 9 ft + 6 ft P = 30 ft 6 ft 8 ft + 8 ft P = 32 ft 8 ft 9 ft 2 ft + 10 ft 5 ft + 5 ft 2 ft P = 24 ft 10 ft P = 20 ft 5 ft

Practice Answers Find the area of the following shapes: 6 ft x 9 ft 6 ft A = 54 ft^2 8 ft x 8 ft A = 64 ft^2 9 ft 2 ft x 10 ft 2 ft A = 20 ft^2 5 ft x 5 ft A = 25 ft^2 10 ft 5 ft
