Definition
Area
Area tells how much two-dimensional space a flat region covers, measured in square units.
What it means
Imagine laying equal square tiles over a shape. The number of tiles needed is its area. A formula such as length × width is a quick way to count the square units in a rectangle.
Remember it
Area is the space inside; picture covering it with square tiles.
Example
A rectangle is 7 cm long and 3 cm wide. It fits 7 rows of 3 one-centimetre squares, so its area is 7 × 3 = 21 cm².
Watch for
Area measures a flat region, not the distance around its edge.
Common mix-up
Perimeter uses length units such as cm; area uses square units such as cm².
Exact meaning
Area is the measure of a two-dimensional region. It is expressed in square units and can be found by covering the region with unit squares without gaps or overlaps.
