Area Review (Parallelograms, Triangles, Trapezoids, Kites)

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height

Front

What is the formula for the area of a trapezoid?

Back

Area = 1/2 × (base1 + base2) × height

Front

What is the formula for the area of a kite?

Back

Area = 1/2 × (diagonal1 × diagonal2)

Front

If the base of a parallelogram is 10 m and the height is 5 m, what is the area?

Back

Area = 10 m × 5 m = 50 m²

Front

A triangle has a base of 6 cm and a height of 4 cm. What is its area?

Back

Area = 1/2 × 6 cm × 4 cm = 12 cm²

Front

A trapezoid has bases of 8 m and 12 m, and a height of 5 m. What is its area?

Back

Area = 1/2 × (8 m + 12 m) × 5 m = 50 m²

Front

What is the area of a rectangle with a length of 10 ft and a width of 4 ft?

Back

Area = 10 ft × 4 ft = 40 ft²

Front

If one diagonal of a kite is 8 ft and the area is 32 ft², what is the length of the other diagonal?

Back

Area = 1/2 × (8 ft × diagonal2) => diagonal2 = 8 ft

Front

What is the area of a rectangle with an area of 72 sq. ft. and a height of 9 ft?

Back

Width = Area / Height = 72 sq. ft. / 9 ft = 8 ft
