Area and Perimeter of Triangles and Parallelograms

This video tutorial covers the calculation of areas for triangles and parallelograms, including cases where the height is outside the triangle. It also briefly touches on finding perimeters. The tutorial provides examples and explains the formulas used, such as base times height for parallelograms and half the base times height for triangles.

What is the formula for the area of a parallelogram?

• Base minus height

• Base times height

• Base divided by height

• Base plus height

In a parallelogram, which side is considered the base?

• The longest side

• The shortest side

• The side opposite the height

• Any of the parallel sides

How do you find the area of a triangle with a base of 6 cm and height of 5 cm?

• 10 square cm

• 30 square cm

• 15 square cm

What should you do if a triangle is oriented in a way that makes it hard to identify the base and height?

• Use the longest side as the base

• Ignore the orientation

• Use the shortest side as the height

• Rotate the triangle
