Area of Parallelograms, Triangles, & Trapezoids

Front

What is the area formula for Parallelograms?

Back

Area = base × height

Front

What is the area of a trapezoid with bases 4 cm and 6 cm, and height 3 cm?

Back

Area = 0.5 × (base1 + base2) × height = 0.5 × (4 + 6) × 3 = 15 cm²

Front

What is the area formula for Triangles?

Back

Area = 0.5 × base × height

Front

In a trapezoid, the bases are always __________.

Back

parallel

Front

What is the area of a rectangle with length 10 in and width 18 in?

Back

Area = length × width = 10 × 18 = 180 in²

Front

What is the height of a parallelogram if the area is 36 cm² and the base is 6 cm?

Back

Height = Area / base = 36 / 6 = 6 cm

Front

What is the area of a triangle with base 8 cm and height 5 cm?

Back

Area = 0.5 × base × height = 0.5 × 8 × 5 = 20 cm²

Front

What is the formula for the area of a trapezoid?

Back

Area = 0.5 × (base1 + base2) × height

Front

If a parallelogram has a base of 12 m and a height of 4 m, what is its area?

Back

Area = base × height = 12 × 4 = 48 m²

Front

What is the area of a trapezoid with bases 5 cm and 7 cm, and height 4 cm?

Back

Area = 0.5 × (5 + 7) × 4 = 24 cm²
