Thank you for your support!

4.MD.A.3 Know and apply the area and perimeter formulas for rectangles in real- world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
