I've got a form with 3 input values and I'm trying to sort them from smallest to highest and then do this.

1. Add together the 2 shortest sides: 40 + 50 = 90.
2. Multiply this number by 2: 90 x 2 = 180.
3. Add the longest length to this number: 180 + 55 = 235.

I've got them sorted and pushed to the inputs array but I can't get my head around adding and multiplying them 😓.

Any help or sugestions guys.

     <form class="calc__container">

        <input 
        data-input 
        type="number"
        id="length"
        placeholder="Length">

        <input 
        data-input 
        type="number"
        id="width"
        placeholder="Width">

        <input 
        data-input 
        type="number"          
        id="hight"
        placeholder="Higth">
         
        <button class="submit__btn hover">Submit</button>


          <div class="ans-container">
            
            <p class="ans__p ">271 cm</p>
          </div>
        
     </form>

        let lInput = document.getElementById('length');
        let wInput = document.getElementById('width');
        let hInput = document.getElementById('hight');

        const submitBtn = document.querySelector('.submit__btn')

        let inputs = []

       submitBtn.addEventListener('click', function (e) {
       e.preventDefault();

          let allpointsArr = [
            Number(lInput.value), 
            Number(wInput.value), 
            Number(hInput.value)
          ];

         allpointsArr.sort(function(a, b){return a - b});
      
           points.push(allpointsArr)
           console.log(points);

          });
