Teaching 4.MD.A.3 – Apply Area and Perimeter Formulas for Rectangles in Real World and Mathematical Problems

 

perimeter-areaMeasurement & Data – 4th Grade

Solve problems involving measurement and conversion of measurements.

CCSS.Math.Content.4.MD.A.3
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.
