Solve the problem.
-A small farm field is a square measuring $280 \mathrm{ft}$ on a side. What is the perimeter of the field? If you double the length of each side of the field, what is the new perimeter?
A) $280 \mathrm{ft}, 1120 \mathrm{ft}$
B) $560 \mathrm{ft}, 2240 \mathrm{ft}$
C) $1120 \mathrm{ft}, 2240 \mathrm{ft}$
D) $560 \mathrm{ft}, 1120 \mathrm{ft}$

The perimeter of a square is given by $4 \times \text{side length}$, so the original perimeter is $4 \times 280 \mathrm{ft} = 1120 \mathrm{ft}$. Doubling each side gives a new side length of $560 \mathrm{ft}$, so the new perimeter is $4 \times 560 \mathrm{ft} = 2240 \mathrm{ft}$.
