Calculate the area and perimeter of an isosceles trapezium. In an isosceles trapezium, the base length angles are equal, making both side legs equal in length.
This calculator uses metres for measurements.
Isosceles trapezium = 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 trapezium P the perimeter of the trapezium
one metre (m) = 3.28083989501312 feet (ft) one metre (m) = 39.3700787401575 inches (in) one square metre (m²) = 10.7639104167097 square feet (ft²) one square metre (m²) = 1550.0031000062 square inches (in²)
