1.8 Perimeter, Circumference & Area ♥ Perimeter is the distance around a polygon ♥ Circumference is the distance around a circle. ♥ Area is the number of square units that a shape encloses. ♥ Perimeter is labeled in units ♥ Circumference is labeled in units ♥ Area is labeled in units squared. Really super duper, extra double triple, uber important!!!

Area Addition Postulate 25 sq ft 45 sq ft 13 sq ft 11 sq ft Total area = 94 sq. ft.
6
To find the area of the shaded region 1.Find the area of the big shape 2.Find the area of the small shape 3.Subtract them 7 units 10 units 3 units 4 units Area of large shape = 70 sq units Area of small shape = 12 sq units Area of shaded region = 58 sq units.
