Please begin working on your warm up.

Please get out your daisies ♥ Cut out your construction ♥ Bring it to me so I can enter your grade ♥ Glue it on the poster paper ♥ Have a seat, get your notes out, and be ready to start section 1.8

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!!!

Trapezoid A = (b 1 + b 2 )h 2 b1b1 b2b2 h Parallelogram A=bh b h

Area Addition Postulate 25 sq ft 45 sq ft 13 sq ft 11 sq ft Total area = 94 sq. ft.

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.
