Warm Up (no trapezoids): Area and Perimeter of Polygons

Front

What is the formula for calculating the perimeter of a triangle?

Back

The perimeter of a triangle is calculated by adding the lengths of all three sides: P = a + b + c.

Front

How do you calculate the area of a triangle?

Back

The area of a triangle can be calculated using the formula: A = 1/2 * base * height.

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated using the formula: P = 2 * (length + width).

Front

How do you find the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: A = length * width.

Front

What is the definition of a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments that connect to form a closed chain or circuit.

Front

What is the formula for the area of a triangle given its base and height?

Back

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

Front

What is the perimeter of a polygon?

Back

The perimeter of a polygon is the total length of all its sides.

Front

How do you calculate the area of a trapezoid?

Back

The area of a trapezoid can be calculated using the formula: A = 1/2 * (base1 + base2) * height.

Front

What is the formula for the perimeter of a trapezoid?

Back

The perimeter of a trapezoid is calculated by adding the lengths of all four sides: P = a + b + c + d.

Front

What units are used to measure area?

Back

Area is typically measured in square units, such as square meters (m²), square feet (ft²), or square yards (yd²).
