Answer:
In the side of the square filde is 'a' unites, then it's area (A) is A=a² square unit....1
Area of a squre (A) 9x² - 24x + 16. (given)
A= 9x²- 24x + 16
=9x²-12x - 12x +16
= 3x (3x- 4) -4 (3x - 4)
= (3x - 4) (3x-4)
= (3x - 4)² ... 2
=from 1 and 2 we get
side square filde = (3x -4) unit
if x =8 unit then
side of square= (3x-4) = (3x8) -4 = 24-4 = 20 unite.
