Answer 1

Answer:

125 %

Step-by-step explanation:

Let side of square be 'a' units (a≠0)

Area = a² sq units

Now each side is increased by 50%

So new side = a' = a + 50% a = a + a/2 = 3a/2

New area = $[\frac{3a}{2} ]^{2}$ = 9a²/4

Increase in area = 9a²/4 - a² = 5a²/4

%increase in area = increase in area/original area X 100

= 5a²/4 ÷ a² X 100 %

= 25 X 5 = 125 %
