Multipled by 5 because the equation previously was: 1a x 1a thus a^2. And if the answer was to increase by 5 it would (1+ 5)a^2 which would yield 36 and if (1x5)a^2 then 5X5 = 25

Answer:

a square with an area of a² is enlarged to a square with an area of 25a².

The side length of the smaller square was changed when The side length was multiplied by 5.

Area = (1a)² = a²

Area = 1a * 5 = 5a ⇒ (5a)² = 25a²

So, your answer would be B. The side length was multiplied by 5
