Find the perimeter of the polygon, the two large sides of which are 6cm each and its two smaller sides are 4cm each.

Since, by definition, the perimeter of a polygon is the sum of all its sides, we need to use this rule when solving this problem. All we need is to add up the measurements of the figure described in the condition, namely:

6 * 2 + 4 * 2 = 20 (centimeters) – the perimeter of the polygon. We double each indicator, due to the fact that we are given two such sides.

Answer: 20 centimeters is the perimeter of the polygon.
