We can check and know these are the correct values by plugging them back into the Perimeter Formula. ★Now we need the Length, which we already know is two times the Width! The variable is being multiplied by six, use Opposite Operation of division to isolate variable, divide both sides by six Now we can replace the L variables in the equation with 2W, which makes the equation solvable for width. (It is expected we have this formula memorized.) The sum of all the sides, the measure of the shape's outline. In this video we are asked for the dimensions of a rectangle when given the perimeter, so the heart of the equation is the…
