Calculate the area and perimeter of a right-angled trapezoid. In a right-angled trapezoid, the angles on one of the sides are 90 °.
This calculator uses feet and or inches for measurements
Right-angled trapezoid = is a trapezoid with 90° angles on one side making the height the same length as one of the legs.
A = (a+b)/2*h P = a+b+ 2 legs where A is the area a is a base length b the other base length h the height of the trapezoid P the perimeter of the trapezoid
