Grade 4 Geometry: Area and Perimeter

Worked examples

Real problems from the practice worksheets, solved one step at a time.

1. Example 1

   Find the area of the rectangle with length 6 units and width 3 units.

   1. Area is the space inside a rectangle. Multiply its length by its width.
   2. Area = length × width = 6 × 3 = 18 square units.

   Answer: 18 square units

2. Example 2

   Find the perimeter of the square with length 11 units and width 11 units.

   1. Perimeter is the distance all the way around the square. Add the four sides.
   2. Perimeter = 11 + 11 + 11 + 11 = 2 × (11 + 11) = 44 units.

   Answer: 44 units

3. Example 3

   Find the area of the square with length 5 units and width 5 units.

   1. Area is the space inside a square. Multiply its length by its width.
   2. Area = length × width = 5 × 5 = 25 square units.
