What widths will make the perimeter greater then 82 cm?Answer by unlockmath(1599)   (Show Source): You can put this solution on YOUR website!Hello, Let's have x represent the width of the shape. Now we can set up the following inequality: x+x+21+21>82 Combine like terms: 2x+42>82 Subtract 42 and divide by 2 to get: x>20 There we go. Everything greater than 20 cm for the width is the answer. Make sense? RJ www.math-unlock.com
