# Scalene Trapezoid

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.

### Scalene Trapezoid Area and Perimeter

#### Calculation

- enter the length of base a in feet and or inches
- length of base b in feet and or inches
- the length of leg c in feet and or inches
- length of leg d in feet and or inches
- the height of the trapezoid in feet and or inches
- decimal precision, the number of digits after the decimal point

#### Results

- the height of the trapezoid in decimal feet
- the area of the scalene trapezoid in decimal square feet
- area in square feet and inches
- the area in decimal square inches
- the area in square inches
- the area in square metres
- the perimeter of the scalene trapezoid in decimal feet
- the perimeter in lineal feet and inches
- the perimeter in decimal inches
- the perimeter in inches
- 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)
one square inch (in²) = 0.00694444444444443 square feet (ft²)
one square foot ( ft²) = 0.09290304 square metres (m²)
square inch (in²) = 0.00064516 square metres (m²)
