Answer:
the length and width of the rectangle are L and W,
then the perimeter is the sum of the four sides: L+W+L+W = 2L + 2W.
Since it is given that “The length is 2 less than 3 times the width”,
we can say: L = 3W -2. Substituting (3W-2 instead of L), the perimeter is:
2L+2W
= 2×(3W−2)+2×W
= (6W−4)+2W
= 8W−4 = 36
Solving for W is left as an exercise for the student.
Since “length is 2 less than 3 times the width”
just triple your result for W, then subtract 2 to get the length
