Area of Trapezoid

base 1 – bottom or top of figure base 2 – bottom or top of figure h h h b b base 1 – bottom or top of figure base 2 – bottom or top of figure height – vertical distance between the two bases Area is always measured in square units. (units²) To calculate the area of a trapezoid, use the formula: A = (b₁ + b₂)h 2

A = (b₁ + b₂)h 2 = (4 + 2)3 = (6)3 = 9 ft² Ms. Brown is planting a garden in the shape of a trapezoid. The lengths of the bases are 4 ft and 2 ft. The height of the garden is 3 ft. Find the area of the garden. A = (b₁ + b₂)h 2 = (4 + 2)3 = (6)3 = 9 ft²

A = (b₁ + b₂)h 2 140 = (7 + b)10 280 = (7 + b)10 280 = 70 + 10b -70 -70 210 = 10b 10 10 b = 21 cm Given the area, height, and a base of a trapezoid, find the length of the other base. A = 140 cm² h = 10 cm b = 7 cm b = ? cm
