Perimeter = The sum of all the sides (all the side lengths added together)
wait elina how do you solve it
L = 2W - 1
2L + 2W = 40
Substitute 2W-1 for L in second equation and solve for W. Insert that value into the first equation and solve for L. Check by inserting both values into the second equation.
