The formula for the perimeter p of a rectangle with length l and width w is p = 2(l+w). find the length of the rectangle shown here if the perimeter is 9 and 1/2 feet. solve the equation for l and justify each step.

L = and L = 3

distribute the bracket on the right side of the formula

P = 2L + 2W

subtract 2W from both sides

P - 2W = 2L

divide both sides by 2

L =

solve for L for P = and W =

L = ( - )/2 = = 3

all it means is function 3
