Area of Trapezoids

Area of Trapezoids. A trapezoid is a quadrilateral with one pair of parallel sides. To find the area of a trapezoid you use the following formula:. A = (b 1 + b 2 )h. 2. Label the parts of the trapezoid to match the formula. b 1. h. b 2. A = (b 1 + b 2 )h. 2. A = (b 1 + b 2 )h. 2.

  1. Area of Trapezoids

  2. A trapezoid is a quadrilateral with one pair of parallel sides. To find the area of a trapezoid you use the following formula: A = (b1 + b2)h 2

  3. Label the parts of the trapezoid to match the formula. b1 h b2 A = (b1 + b2)h 2

  4. A = (b1 + b2)h 2 b1 = base1 b2 = base2 h = height When you add (base1 + base2 ) it doubles the size of the trapezoid. base1 base2 base2 base1 b2 b1

  5. Find the area of the trapezoid. b1 = 5 m b2 = 8 m h = 4 m b2 = 8 m b1 = 5 m b1 + b2 A = (13)4 A = (b1 + b2)h 2 2 A = 52 A = (5 + 8)4 2 2 A = 26 m²

  6. Find the area of the trapezoid. A = (b1 + b2)h 2 h A = (3 + 8)5 b1 b2 2 b1 + b2 A = (11)5 b1 2 b2 A = 55 2 h = 5 cm b1 = 3 cm A = 27.5 cm² b2 = 8 cm

  7. Find the area of the trapezoid. A = (b1 + b2)h b1 b2 2 h A = (2 + 6)3 b1 b2 2 b1 + b2 A = (8)3 2 b1 = 2 km A = 24 b2 = 6 km 2 h = 3 km A = 12 km²

  8. Find the area of the trapezoid. A = (b1 + b2)h b2 2 b1 h b2 b1 A = (34 + 16)13 2 b1 + b2 A = (50)13 2 b1 = 34 mm A = 650 b2 = 16 mm 2 h = 13 mm A = 325 mm²
