In this animated math video, Aaron helps his grandfather build a garden in the backyard. They need to calculate the area, which Aaron learns is the amount of space covered by a 2D shape or surface. Area can be calculated by using 1 cm squared paper and counting the squares. Aaron also learns the formulas for calculating the area of a rectangle, a parallelogram, a triangle, and a polygon. Area is expressed in square centimetres, square metres, or square kilometres.
