Answer:
3/4, 75%
Step-by-step explanation:
Let side of original square =x cm
It's perimeter = 4x=p(given)
Side of new square =x/2 cm
Perimeter of new square = 4× new side = 4× x/2 = 2x cm= p/2 cm
Area of new square = side × side
= x/2 × x/2 = (x^2)/4 sq cm
Change in area = (original area - new area)/original area
=(x^2-x^2/4)/x^2
=(3x^2/4) × (1/x^2)
=3/4 of original area
Percentage = 3/4×100%=75%
