Write and solve an inequality to find the values of x for which the perimeter of the rectangle is less than

116.

A rectangle has a width of x and a length of x+4

The perimeter  =  2 (W + L)  ......so

 

2( x  +  x + 4) < 116      divide both sides by 2

 

x + x + 4   <   58           subtract 4 from both sides, simplify the left side

 

2x  <  54                       divide both sides by 2, again

 

x <  27   ....... so the width is < 27   and the length is < 31

 

 

cool cool cool
