The video tutorial explains how to calculate the area of rectangles, parallelograms, and triangles. It begins with an introduction to the concept of area, using rectangles as an example. The formula for calculating the area of a rectangle is given as length times width. The tutorial then moves on to parallelograms, explaining that the area is calculated using base times height, similar to rectangles. Finally, the video covers triangles, highlighting that the area is half of the base times height, as a triangle is essentially half of a rectangle or parallelogram.

What does the area of a shape tell us?

• The perimeter of the shape

• The volume the shape occupies

• The amount of space the shape covers

• The color of the shape

What is the formula for the area of a rectangle?

• Area = length x width

• Area = (length + width) / 2

• Area = length / width

• Area = length + width
