The formula for the area of a rectangle is a=lw. solve the formula for w. then describe the meaning of the transformed formula.

To solve for W, you have to get it by itself.

To do this, start with your formula,

A=LW

You have to divide both sides by L  to get W  by itself.

A/L = W

Now that the formula has been transformed, to A/L = W, here's the meaning:

If you divide A by L, you will get W. (If you divide Area by Length, you will get the width).

step-by-step explanation:

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm
