the perimeter of a rectangle is 66 meters. the length is 1 more than three times the width what are the dimentions?
P=2[L + W], but we have,
3W + 1=L, we sub
66=2[3W + 1 +W]
66=6W + 2 + 2W
64=8W divide both sides by 8
W=8 meters-the width of the rectangle, then we have,
L=(8 X 3) + 1=25 meters- the length of the rectangle
