Area : The amount of unit squares that is needed to cover a 2-dimensional shape.
Centimeter : A centimeter ($cm$) is $\frac{1}{100}$ of a meter.
Factor : If a natural number is divisible by a second natural number, that second natural number is called a factor of the first natural number. For example the factors of 12 are 1,2,3,4,6 and 12.
Length : Length is the attribute of a one-dimensional shape that can be measured with a measuring tape.
Rectangle : A rectangle is a quadrilateral with 4 right angles. Two opposing sides in a rectangle have the same length. They are sometimes referred to as the width and the length of the rectangle. To calculate the area of an rectangle one can multiply the width of the rectangle by the length of the rectangle. A square is the special case of a rectangle in which all side lengths are the same. Every rectangle is a parallelogram.
Scale : Scale refers to the size of a shape. A scale drawing changes a shape to a similar shape of a different size.
Square centimeter : Square centimeter or $cm^2$ is a unit of measurement for measuring area. 1 square centimeter is the area of a square with side length 1 $cm,$ so 10,000 $cm^2$ are one $m^2.$
In a scale drawing with a scale 1:10 a rectangle is 2 cm long and 4 cm wide. What is the actual area of the rectangle in $cm^2$?
