Length of a Rectangle SideDate: 8/24/96 at 19:28:24 From: Anonymous Subject: Length of a Rectangle I need an equation for this problem: The length of a rectangle is 9 cm more than half the width. Find the length if the perimeter is 60 cm. Date: 8/25/96 at 15:15:32 From: Doctor Robert Subject: Re: Length of a Rectangle Let x be the width of the rectangle. Then x/2 is half the width, and the length is x/2 + 9. Now the perimeter - which is 60 cm - would be 2 widths plus 2 lengths, so 60 = 2(x) + 2(x/2 + 9) Can you take it from here? -Doctor Robert, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
