U7L4 Area of Trapezoids, Rhombuses, and Kites

Front

What is the formula for the area of a rhombus?

Back

Area = (d1 * d2) / 2, where d1 and d2 are the lengths of the diagonals.

Front

Calculate the area of a rhombus with diagonals d1 = 16 cm and d2 = 12 cm.

Back

Area = (16 * 12) / 2 = 96 cm².

Front

What is the area of a rhombus with diagonals d1 = 5 cm and d2 = 6 cm?

Back

Area = (5 * 6) / 2 = 15 cm².

Front

What is the formula for the area of a kite?

Back

Area = (d1 * d2) / 2, where d1 and d2 are the lengths of the diagonals.

Front

Calculate the area of a kite with diagonals d1 = 18 m and d2 = 10 m.

Back

Area = (18 * 10) / 2 = 90 m².

Front

What is the formula for the area of a trapezoid?

Back

Area = (1/2) * (b1 + b2) * h, where b1 and b2 are the lengths of the bases and h is the height.

Front

Calculate the area of a trapezoid with bases b1 = 10 cm, b2 = 20 cm, and height h = 9 cm.

Back

Area = (1/2) * (10 + 20) * 9 = 135 cm².

Front

What is the area of a trapezoid with bases 15 cm and 25 cm, and height 6 cm?

Back

Area = (1/2) * (15 + 25) * 6 = 120 cm².

Front

What is the area of a trapezoid with bases 12 cm and 18 cm, and height 4 cm?

Back

Area = (1/2) * (12 + 18) * 4 = 60 cm².

Front

What is the area of a trapezoid with bases 5 cm and 15 cm, and height 3 cm?

Back

Area = (1/2) * (5 + 15) * 3 = 30 cm².
