A quadrilateral is any closed four-sided figure. There are two types of quadrilaterals: concave and convex. A concave quadrilateral has a part that goes into the shape, while a convex quadrilateral has angles all on the outside corners of the shape.

An area is always given in units of length^2 (“length squared”). In other words, if the dimensions of the rectangle are given in inches, the units for area will be in^2.
Read MoreThe perimeter of a rectangle is the length of the boundary around the figure. You can find the perimeter of a rectangle by calculating the sum of the length of its four sides. Sometimes you’ll see the perimeter formula as P=2l+2w, where l is the length of the rectangle, and w is the width of the rectangle.
