area grade 3 worksheets

📐 Topic Summary

Area is the amount of space inside a shape. Think of it like the amount of carpet you'd need to cover the floor in your room! We measure area in square units, like square inches or square centimeters. To find the area of a rectangle or square, you multiply its length by its width.
