The area is the length times the width. Find area of shapes by counting unit squares. Some shapes will require combining partial square units to find area.
For example - A rectangle is 5 centimeters long and 4 centimeters wide. What is its area?
Area = Length * width
The length is 5 centimeters. The width is 4 centimeters. So the area is 5 times 4 square centimeters.
= 20 square centimeters
