Question 828428: the lenght of a rectangle is 99 centimeters. find all possible values for the width of the rectangle if the perimeter is at least 240 centimeters Answer by Seutip(231) (Show Source):
You can put this solution on YOUR website! Let x- be the width
In finding the Perimeter, we use the formula
P=2length+2width
So,
240 = 2(99) + 2x
240 = 198 + 2x
42 = 2x
21 = x
So the width should be 21 cm, to have a length of 99 cm and a perimeter of 240 cm.
Hope that helps! :)
