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

#12 1/2 / 1 1/4 = 10#

#17 1/4 / 1 1/4 = 13 8/10#

it is easier to it in decimal form

#12.5 / 1.25 = 10#

#17.25 / 1.25 = 13.8#

area equals length times width

#10 * 13.8 = 138#
