Centimeter : A centimeter ($cm$) is $\frac{1}{100}$ of a meter.
Equilateral : A polygon that has side lengths that are all equal is called equilateral polygon.
Length : Length is the attribute of a one-dimensional shape that can be measured with a measuring tape.
Perimeter : The perimeter of a two-dimensional shape is the length of the boundary of the shape. For a polygon this is the same as the sum of all the side lengths. For example a triangle with side lengths 1, 2 and 3cm has a perimeter of 1+2+3=6cm. The perimeter of a circle is referred to as its circumference.
Quadrilateral : A quadrilateral or quadrangle is a polygon with four corners. Rectangles, trapezoids, kites, rhombuses, squares and parallelograms are all specific kinds of quadrilaterals. The sum of the interior angles in a quadrilateral is always $360^{\circ}.$
Sum : A sum is the result of an addition.
What is the perimeter in cm of an equilateral quadrilateral with sides that are 2 cm long?
