Area and Perimeter

Scalene Trapezoid

Spike VM

Calculate the area and perimeter of a scalene trapezoid. A scalene trapezoid is a shape where two different length bases run parallel to each, and the connecting legs have different lengths.

This calculator can be used for different types of trapezoids (isosceles, right-angled, obtuse) when you know the length of all four sides.

Scalene = trapezoid with all sides having a different length, and the four angles are unequal.

Results

  1. the height of the trapezoid in decimal feet
  2. the area of the scalene trapezoid in decimal square feet
  3. area in square feet and inches
  4. the area in decimal square inches
  5. the area in square inches
  6. the area in square metres
  7. the perimeter of the scalene trapezoid in decimal feet
  8. the perimeter in lineal feet and inches
  9. the perimeter in decimal inches
  10. the perimeter in inches
  11. the perimeter in metres
Formula
0.5hy= √(s(s-c)(s-d)(s-y))
A = (a+b)/2*h
P = a+b+c+d
where h is the height of the trapezoid
y the length of the base = b  a
s = 0.5(c+ d + y)
a is the short base length
b the long base length
c the length of a leg
d the length of the other leg
A is the area
P the perimeter of the trapezoid


Conversions
one square foot ( ft²) = 144 square inches (in²)
