Explanation:

first you need to see how many times $1 \frac{1}{4}$ $1 1/4$ goes into both $12 \frac{1}{2}$ $12 1/2$ and $17 \frac{1}{4}$ $17 1/4$ . this will tell you how many feet each unit represents.

$12 \frac{1}{2} / 1 \frac{1}{4} = 10$ $12 1/2 / 1 1/4 = 10$

$17 \frac{1}{4} / 1 \frac{1}{4} = 13 \frac{8}{10}$ $17 1/4 / 1 1/4 = 13 8/10$

it is easier to it in decimal form

$\frac{12.5}{1.25} = 10$ $12.5 / 1.25 = 10$

$\frac{17.25}{1.25} = 13.8$ $17.25 / 1.25 = 13.8$

area equals length times width

$10 \cdot 13.8 = 138$ $10 * 13.8 = 138$
