Square measure

In this lesson, we will learn:

• Square measure refers to the squared units that are used to measure area
• How to count the square measure of areas shown by unit square figures
• Comparing between metric units and squared metric units

Notes:

• Square measure refers to the units we use to measure area
• A unit square is a square with a measure of 1 unit on each side
• Units can be in metric units (i.e. m², cm², mm²) or other customary units (i.e. ft², in², yd²)

• Different dimensions (1-dimensional or 2-dimensional) correspond to geometric properties of shapes (perimeter or area) as well as their units:

• The square measure of area can be thought of as the number of unit squares that cover the 2D shape. You can count each unit square one by one to find the area.
• If you have a rectangular figure of unit squares, think of it as an array:

• Converting between metric units: meters (m), centimeters (cm), millimeters (mm)

• Converting between squared metric units: m², cm², mm²
