Farmer Ann builds 2 pig-pens using fencing. How big is each pig pen? How much fencing was used for each pig pen? 1 m 2 2 Area = 6 m Area = 5 m Perimeter = 10 m Perimeter = 10 m 1 m2 For every polygon (flat shape) we can find the size of the area 1 m (the surface) 1 m2 Imagine: the space to move Area = 6 m2 & the perimeter (the edge) Imagine: walking ...
Perimeter of a Rectangle •The perimeter is the distance around a figure. •The formulas are: P = 2L + 2W P = 2 (L + W) 15 in. •Measured in single units. 8 in. P = 2(8 in.) + 2(15 in.)P = 2 (8 in. + 15 in.) P = 16in. + 30 in. P = 2 (23 in.) P = 46 in. P = 46 in. Perimeter of a Square •The ...
