Calculate the area and perimeter of an isosceles trapezoid. In an isosceles trapezoid, the base length angles are equal, making both side legs equal in length.
This calculator uses feet and or inches for measurements
Isosceles trapezoid = equal base angles with two legs (sides) of equal length.
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
