# 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

Base Length a m
Base Length b m
Height m
Decimal Precision

#### Results:

Length of Diagonal m
###### Area of the Trapezium
Square Metres
Square Feet ft²
Square Inches in²
Metres m
Feet ft
Inches in

#### Calculation

1. enter the length of base a in metres
2. length of base b in metres
3. the height of the trapezium in metres
4. decimal precision, the number of digits after the decimal point

#### Results

1. the length of the diagonal in metres
2. the area of the right-angled trapezium in square metres
3. the area in square feet
4. the area in square inches
5. the perimeter of the right-angled trapezium in metres
6. the perimeter in feet
7. 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)
