The Carpet House owner wants to put a carpet calculator on his website so that visitors can estimate the amount of carpet they will need to purchase. A form named carpet is used to collect the length and width values, and to display the value of the calculated square feet. A 15% allowance is typically included for room irregularities and unavoidable waste. Complete the code for the following function to provide that functionality. function ComputeSquareFeet( ) { /* get the values for length and width */ /* set the value for the overage */ /* compute the correct number of square feet needed */ /* set the value of the appropriate form input element to display the calculated total*/ }
