  1. Please begin working on your warm up.

  2. 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

  3. 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. Really super duper, extra double triple, uber important!!! • Perimeter is labeled in units • Circumference is labeled in units • Area is labeled in units squared.

  4. Parallelogram A=bh Trapezoid A = (b1 + b2)h 2 b1 h h b b2

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

  6. To find the area of the shaded region • Find the area of the big shape • Find the area of the small shape • Subtract them Area of large shape = 70 sq units Area of small shape = 12 sq units Area of shaded region = 58 sq units. 10 units 4 units 3 units 7 units

  7. Midpoint Formula

  8. Distance Formula
