How to find the area and perimeter of a rectangle?
A rectangle is a four sided-polygon, which has equal opposite sides and 4 interior right angles.
Answer: The area of a rectangle = length × breadth, perimeter of a rectangle = 2 × (length + breadth).
Let us apply these formulas using the following example.
Let us use the formula given below to find the area and perimeter of a rectangle.
- Area of a rectangle = length × breadth
- Perimeter of a rectangle = 2 × (length + breadth)
Find the area of a rectangle with 4 units of length and 5 units of breadth.
Area of the rectangle = 4 × 5 = 20 square units
Perimeter of the rectangle = 2 × (4 + 5) = 18 units
