A woman bought an article for #225 out of #1000, how much was her change? (a) #755 (b) #225 (c) #775 (d) #25

The woman paid with #1000 and the article cost #225.
Change = Total money - Cost of article

The correct option is (c).
The change was $\boxed{\text{(c) \#775}}$.

The correct option is (a).
The value is $\boxed{\text{(a) 14}}$.

The correct option is (a).
The result is $\boxed{\text{(a) \#44.37}}$.

Length ($L$) = $7 \text{ cm}$
Width ($W$) = $3 \text{ cm}$

The correct option is (a).
The perimeter of the rectangle is $\boxed{\text{(a) 20 cm}}$.

Side ($s$) = $3 \text{ cm}$

The correct option is (c).
The area of the square is $\boxed{\text{(c) 9 cm}^2}$.

Section B: Theory

Length ($L$) = $10 \text{ cm}$
Width ($W$) = $9 \text{ cm}$

The area of the rectangle is $\boxed{90 \text{ cm}^2}$.
