the length of a rectangle is reduced by 22 % . by what % would the width have to be increased to maintainthe original area ?
"sol . required change = ( 22 * 100 ) / ( 100 - 22 ) = 28 % c"
multiply(divide(subtract(const_1, divide(subtract(const_100, 22), const_100)), divide(subtract(const_100, 22), const_100)), const_100)
