Area and Perimeter of Triangles and Quadrilaterals

Front

What is the formula for the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of its three sides: P = a + b + c.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: A = 1/2 * base * height.

What is the formula for the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula: A = base * height.

Front

What is the formula for the perimeter of a parallelogram?

Back

The perimeter of a parallelogram is given by the formula: P = 2 * (base + side length).

What units are used to measure perimeter?

Back

Perimeter is measured in linear units, such as cm, m, ft, etc.

Front

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

Back

You can rearrange the area formula: height = (2 * area) / base.
