Answer:
x² - 10
Step-by-step explanation:
The area of the shaded region is the total area subtracted by the area of the non-shaded region.
Total:
Square with side s = x.
The area of a square of side s is A = s².
So
At = s² = x²;
Non-shaded:
Rectangle, of base b = 2 and side s = 5.
The area of a rectangle with base b and side s is A = b*s.
So
Ans = b*s = 2*5 = 10
Shaded:
At = At - Ans = x² - 10
