165 m²

Answer 2

9514 1404 393

Answer:

• 196
• 361
• 165

Explanation:

The original side length is 14 m, so the area is (14 m)² = 196 m².

The longer side length is 14 m + 5m = 19 m, so the area is (19 m)² = 361 m².

The increase in area is ...

361 m² -196 m² = 165 m²

The area increases from 196 m² to 361 m², which is an increase of 165 m².
