How To Find The Surface Area Of A Rectangle
Let's look at the geometric characteristics
of a rectangle. But first, please review the definition of Surface Area Of Three-Dimensional
Shapes, Right Angle, and Exponents.
- A rectangle has some unique features. It has four sides, however all four sides cannot
be equal in length. The two sides that are opposite from each other (widths) may be the
same lengths. The other two sides, the one on the top and the one on the bottom (lengths),
may have the same length as each other. One more very important characteristic about rectangles are the length, width, and height are NOT required to be the same length.
- Another unique feature of a rectangle, all sides are perpendicular
to the side at its endpoints.
- Special note, the side
of a rectangle must be greater than zero.
Surface Area Of A Rectangle Formula
Formula = (Length × Height) + (Length × Height) + (Width × Height) + (Width × Height) + (Length × Width) + (Length × Width) =
Formula = ((L × H) + (W × H) + (L × W)) + ((L × H) + (W × H) + (L × W)) =
Formula = 2 × (L × H) + 2 × (W × H) + 2 × (L × W) =
Formula = 2 × ((L × H) + (W × H) + (L × W))
