Question

If the sides of square is increased by 400%. Find the% change in its area​

Answer 1

Answer:

160000%

Step-by-step explanation:

Let the sides be x

Area 1

side*side=x*x

= $x^{2}$

Area 2

(Sides become x+400)

side*side=x+400*x+400

= $x+400^{2}$

= $x^{2}$+1,60,000

Hence, area increases by 160000%
