Answer 2

Answer:125%

Step-by-step explanation:

let edge=x

so area=6x square

new edge=50/100x + x

=3/2x

TSA=6(3/2x)square= 6(9x square/4)= 27x square/2

% increase=Increase/original*100

Increased value=27x square/2 - 6x square

=27x square- 12x square/2

=15x square/2 = 7.5x square

% increase= 7.5x square/6x square * 100

= 7.5/6*100                       (x squares are cancelled during division)

=75/6*10

=125%
