2
Parallelograms Area & perimeter A = bh P = 2 l + 2 w Area & perimeter A = ½ bh P = add the exterior sides Identify the base and height by the right angle Triangles

3
Trapezoid Area = (b 1 + b 2 ) h 2 Perimeter = add the bases and legs together Identify the base and height by the right angle

4
Circles Area = πr 2 (r is radius) Circumference = πd (d is diameter)

5
Find the area of the shaded region ♥Find the area of the big shape…. ♥Find the area of the little shape… ♥Subtract them. ♥Label your answer. 5 ♥ 10 ♥ A = 5 x 10 = 50 A = 3.14 x 2.5 2 = 19.625 Area of shaded region = 50 – 19.625 = 30.375 sq. ♥
