Area is in square units.

Square the factor: 5^2 = 25

Answer: Area of old rectangle is multiplied by 25

Step-by-step explanation:

Original rectangle

  • Length = 5 cm
  • Width = 2 cm

Area = 2 · 5 = 10 cm²

New rectangle

  • Length = 5 · 5 = 25 cm
  • Width = 2 · 5 = 10 cm

Area = 25 · 10 = 250 cm²

The area of the new rectangle = area of old rectangle × 25
