Area of Parallelograms, Triangles, and Trapezoids

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

If the base of a triangle is 10 ft and the height is 5 ft, what is the area?

Back

Area = 1/2 × 10 ft × 5 ft = 25 ft²

Front

What units are used to measure area?

Back

Square units (e.g., ft², yd², m²)

Front

How do you find the height of a parallelogram if you know the area and the base?

Back

Height = Area ÷ base

Front

What is the area of a rectangle with a length of 8 m and a width of 3 m?

Back

Area = length × width = 8 m × 3 m = 24 m²

Front

If a trapezoid has bases of 6 m and 10 m, and a height of 4 m, what is its area?

Back

Area = 1/2 × (6 m + 10 m) × 4 m = 32 m²

Front

What is the area of a triangle with a base of 12 cm and a height of 9 cm?

Back

Area = 1/2 × 12 cm × 9 cm = 54 cm²

Front

What is the area of a parallelogram with a base of 5 m and a height of 7 m?

Back

Area = 5 m × 7 m = 35 m²
