The length of a rectangle is 2 meters longer than three times the width. Use l for the length and w for the width of the rectangle

Is the problem asking for an expression that relates length to width?  There is not enough information here.

If you don't have additional information
let w =  width
then 3w+2=length
The perimeter is then 2w + 2(3w+2)
The area is w (3w +2)

length = 2 more than 3 times the width, with units of meters


L = 2+ 3W


perimeter = 2L + 2W = 4+6W + 2W = 8W +4 meters


area = LW= 2W +3W^2 square meters



usually these problems will give some additional information, such as the perimeter or the area then you could solve for L, W and A or P


Let's say the perimeter was 36 meters, then 8W+4 = 36

8W = 36-4 =32

W =32/8 = 4 meters

L=2+3W = 2 + 3(4)= 2 +12 = 14 meters

and Area =A = LW = 14 x 4 = 56 square meters
