  1. 10.3 Area of Parallelograms and Trapezoids

  2. Area of Rectangle height base Area = base * height

  3. Area of Parallelogram Click here height base Area of a parallelogram = base*height

  4. Find the missing value Area = ? cm Area = 6 cm * 3.5 cm 6 cm Area = 21 cm2 3.5 cm

  5. Find the missing value Area = 120 in2 120 = 8*b base = 15 in 8 in ? in

  6. Find the missing value Area = 96 cm2 96 = 12*h height = 8 cm ? cm 12 cm

  7. Area of a Trapezoid b2 Click here h b1 Area of a trapezoid =

  8. Find the missing value 5 cm Area = ? cm2 2.5 cm Area = 1(5 + 3)(2.5) 2 3 cm Area = 10 cm2

  9. Find the missing value 12 cm Area = 45 cm2 h 45 = 1(12 + 6)h 2 6 cm 45 = 1(18)h 2 45 =9h h = 5 cm

  10. Find the missing value 10 in Area = 30 in2 30 = 1(4)(10 + b1) 2 4 in 30 = 2(10 + b1) b1 30 = 20 + 2b1 10 = 2b1 b1 = 5 in

  11. Find the missing value b2 Area = 42 ft2 42 = 1(6)(8 + b2) 2 6 ft 42 = 3(8 + b2) 8 ft 42 = 24 + 3b2 18 = 3b2 b2 = 6 ft
