Question

Hi can someone pls help me, I’m confused

Answer 1

E. 72w²

Step-by-step explain:

Area I = a × a

= 9w × 9w

= 81w²

Area II = a × a

= 3w × 3w

= 9w²

Shaded area = Area I - area II

= 81w² - 9w²

= 72w²

Answer 2

(E) 72 w^2 is the answer

Explanation:

outer square area is 81 w^2

inner square area is 9 w^2

subtracting outer - inner we can get the shaded area

so 81 -9= 72w^2
