Here is a PDF version of the workbook containing lots of practice.

We are often required to calculate the area and perimeter of objects or spaces in 2 dimensions (flat surface like a piece of paper).

In real life, this skill is helpful when designing living spaces or calculating the amount of fencing required to enclose a certain piece of land, etc.

Perimeter is the length and width around the object – the sum of all outer sides.

Area – the 2 dimensional space surrounded by the sides of the shape.

The two shapes we are looking at in this lesson are rectangle and square.

A square is also a rectangle, but a regular rectangle. “Regular” means all sides and angles are equal.

We develop formulas for both area and perimeter and analyze different situations.
