# Task:
Based on the received dimensions, `a` and `b`, of an ellipse, calculare its area and perimeter.
## Example:
```python
Input: ellipse(5,2)
Output: "Area: 31.4, perimeter: 23.1"
```
**Note:** The perimeter approximation formula you should use: `π * (3/2(a+b) - sqrt(ab))`

## Have fun :)

    perimetro = str(round(math.pi *( 3/2*(a+b) - math.sqrt(a*b)),1))
    return "Area: "+area +", perimeter: "+perimetro
