Write a second converttoinches() with two double parameters, numfeet and numinches, that returns the total number of inches. ex: converttoinches(4.0, 6.0) returns 54.0 (from 4.0 * 12 6.0).

Answer is in java language

Explanation:

I am writting the code with comments in lines that starts with "//".

//First write the method converttoinches having two input parameters

// 1st param numfeet

// second param numinches

// public is a access modifier in which this method can be accessed

// from any class

//double is a return type as we have both input param as double so the

// the return value will also be double as well

public double converttoinches(double numfeet, double numinches) {

// In programming languages any numeric value that is in parenthesis

// will execute first so as we want to multiple numfeet with 12 in order to

//get number of inches in feet and then add those values with //numinches

// return will send the result from this function to where its being called.

       return (numfeet * 12) + numinches;

   }

that would be my answer.
