Answer 3

To solve this expression, we'll add the two distances first and then multiply the result by 2. Let's break it down step by step:

1. Add the two distances: 2дм 2см + 5дм 5см

   Adding the centimeters separately: 2см + 5см = 7см

   Adding the decimeters separately: 2дм + 5дм = 7дм

   So the sum of the two distances is 7дм 7см.

2. Multiply the sum by 2: 7дм 7см × 2

   Multiplying the centimeters separately: 7см × 2 = 14см

   Multiplying the decimeters separately: 7дм × 2 = 14дм

   So the final result is 14дм 14см.

Therefore, (2дм 2см + 5дм 5см) × 2 equals 14дм 14см.
