# What is the perimeter of the polygon in the diagram?

Perimeters and areas are one of the most important topics in mathematics. Different shapes have different formulas for areas and perimeters. They have many practical applications too. Let's solve a problem related to the perimeter of a polygon.

## Answer: The perimeter of the above figure is 42 cm.

Let's understand the solution.

**Explanation:**

To find the perimeter of a shape, we add up the length of its sides.

Hence, according to the given figure,

The perimeter of the solid is: 9 + 2 + 6 +10 + 3 + 12 = 42.
