##### Formula
```A = 𝝅/4D²+LD
P = 𝝅D+2L
where A is the area of the kite
D the diameter length
L the overall length minus the diameter
P the perimeter of the kite
```

##### 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)
