Question

Which expression represents the area of theshaded region?52

Answer 1

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
