Area & Perimeter. Area Area: The space that an object covers. We measure this by multiplying the length of one side by the width of one side. For example:

in square units. 8 x 3 = 24 sq in The area of the rectangle is 24 sq in 8 3 Perimeter Perimeter: The distance around a shape. We measure perimeter by adding up all the sides. For example: The length is 8 and the width is 3. Go ahead and label the two missing sides, and then add all 4 sides together. 8 + 8 + 3 + 3 = 22 in You/
