Rectangles, Parallelograms, Triangles, and Composite Figures

Front

What is the formula for the area of a rectangle?

Back

Area = length × width

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height

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

How do you find the area of a parallelogram?

Back

Area = base × height

Front

What is a composite figure?

Back

A composite figure is a shape that is made up of two or more simple shapes.

Front

If a rectangle has a length of 10 cm and a width of 5 cm, what is its area?

Back

Area = 10 cm × 5 cm = 50 cm²

Front

What is the area of a triangle with a base of 6 m and a height of 4 m?

Back

Area = 1/2 × 6 m × 4 m = 12 m²

Front

What is the relationship between the base and height of a triangle?

Back

The base and height are perpendicular to each other and are used to calculate the area.

Front

How do you calculate the area of a composite figure?

Back

Calculate the area of each simple shape and then sum them up.

Front

What is the area of a rectangle with an area of 36 sq. in. and one side length of 6 in.?

Back

The other side length is 6 in. (Area = length × width, so 36 = 6 × width).
