Select a specific type of trapezium/trapezoid below
The perimeter of a right trapezium, also known as a right trapezoid, is the sum of the lengths of its four sides.
A right trapezium is a four-sided figure with two parallel sides and two non-parallel sides, where one angle is a right angle (90 degrees).
Real-life examples of right trapeziums include the shape of many roofs, where the top part is wider than the bottom, such as in a typical house roof. It can also be seen in the shape of some architectural features, like windows or doorways with a sloped or angled top.
The formula for determining the perimeter of a right trapezium/trapezoid is defined as:
\(P\): the perimeter of the trapezium/trapezoid
\(AB\): the length of side AB
\(BC\): the length of side BC
\(CD\): the length of side CD
\(AD\): the length of side AD
The SI unit of perimeter is: \(meter\text{ }(m)\)
