Question 650165: a perimeter of a rectangle is 78 feet. its length is seven feet more than its width. what are the dimensions of the rectangle Answer by sachi(548) (Show Source):
You can put this solution on YOUR website! let the width is w
then length is w+7
so perimeter=2(w+7+w)=78
or 2w+7=78/2=39
or 2w=39-7=32
or w=32/2=16 & l=16+7=23
