This challenging worksheet asks third graders to work backward and apply formulas. Multiple choice problems find the width of a rectangle with 42 square cm of area and a 7 cm length, the perimeter of a 15 m by 10 m playground, two rectangles that share 24 square cm, and how many 4 cm square tiles cover a 12 cm by 8 cm space.
Fill-ins find side length from a 36 cm square perimeter, area of a 15 m by 2 m hallway, and the side of a 25 square m garden. Students build the flexible thinking real measurement needs.
