Area of Parallelograms, Triangles, and Trapezoids

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 triangle?

Back

Area = (1/2) × Base × Height

Front

Find the area of a parallelogram with a base of 30 m and a height of 25 m.

Back

Area = Base × Height = 30 m × 25 m = 750 m²

Front

Find the area of a parallelogram with a base of 45 mm and a height of 6 mm.

Back

Area = Base × Height = 45 mm × 6 mm = 270 mm²

Front

What is the area of a rectangle with a length of 15 in and a width of 12 in?

Back

Area = Length × Width = 15 in × 12 in = 180 in²

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

What is a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

Front

What is the height of a triangle?

Back

The height of a triangle is the perpendicular distance from the base to the opposite vertex.

Front

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

Back

Area = (1/2) × Base × Height = (1/2) × 10 cm × 5 cm = 25 cm²

Front

What is the area of a trapezoid with bases of 8 m and 12 m, and a height of 5 m?

Back

Area = (1/2) × (Base1 + Base2) × Height = (1/2) × (8 m + 12 m) × 5 m = 50 m²
