1.	Think, is rectangle a regular shape? If you want to find a formula for the perimeter of a rectangle. What will you do?
Answer» No, rectangular is not a regular shape. Because it’s all sides are not equal measurement. We know that opposite sides of a rectangle are equal. i.e. perimeter = 2 × length + 2 × breadth Therefore formula for the perimeter of rectangle perimeter = 2 × (length + breadth) This is the perimeter of rectangle. Now perimeter of given rectangular shape = 2 × (15 + 5) = 2 × 20 = 40 m.

Answer»

No, rectangular is not a regular shape.
Because it’s all sides are not equal measurement.
We know that opposite sides of a rectangle are equal.

i.e. perimeter = 2 × length + 2 × breadth

Therefore formula for the perimeter of rectangle

perimeter = 2 × (length + breadth)

This is the perimeter of rectangle.

Now perimeter of given rectangular shape = 2 × (15 + 5)

= 2 × 20 = 40 m.
