Answer 1

The first thing you should do in this case is to know the following unit conversion:
 1 foot = 12 inches
 We then make the following rule of three:
 1 foot ----> 12 inches
 14 feet --> x
 We then clear the value of x:
 x = (14/1) * (12)
 x = 168 inches
 Answer:
 Marta has 168 inches of wire
