# Area and Perimeter

# Right-Angled Trapezium

Calculate the area and perimeter of a right-angled trapezium. In a right-angled trapezium, the angles on one of the sides are 90 °

This calculator uses metres for measurements.

Right-angled trapezium = is a trapezium with 90° angles on one side making the height the same length as one of the legs.

### Right Trapezium Area and Perimeter

#### Calculation

- enter the length of base a in metres
- length of base b in metres
- the height of the trapezium in metres
- decimal precision, the number of digits after the decimal point

#### Results

- the length of the diagonal in metres
- the area of the right-angled trapezium in square metres
- the area in square feet
- the area in square inches
- the perimeter of the right-angled trapezium in metres
- the perimeter in feet
- the perimeter in inches

##### Formula

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

##### Conversions

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)
