Problema Solution
Geometry Dave and Jane Wells have a new rectangular driveway. The perimeter of the driveway is 168 feet. The length is 12 feet longer than three times the width. What are the dimensions of the driveway?
Answer provided by our tutors
PERIMETER OF THE DRIVE WAY = 168 FEET
LET THE BREADTH BE = X m
then lenghth = 12 + 3x
then
we know
perimeter of a rectangle is = 2(L+B) = 168
=> 2(12+4x) = 168
=> x = 72/4 = 18m
so l = 12+ 54 = 66 m
