The area of a rectangle is 56 square centimeters. The length of the rectangle is 8 centimeters, and the width is three less than a number. What is the number?

OpenStudy (jadeishere):

Area = length multiplied by width 56 = (8) multipled by (w) 56 / 8 = w w = 7 7 + 3 = 10 10 is the number :) This should be posted in the "Mathematics" subject, for future reference :) Welcome to Openstudy!
