Question 359333: The perimeter of a Desktop is 108 inches, the width is 14 inches shorter than the length,write an eqaution to represent the perimeter and determine the dimension of the desktop? Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! W=L-14
2L+2W=108
2L+2(L-14)=108
2L+2L-28=108
4L=108+28
4L=136
L=136/4
L=34 ANS. FOR THE LENGTH.
W=34-14=20 ANS. FOR THE WIDTH.
PROOF:
2*34+2*20=108
68+40=108
108=108
