1. Convert Units:

* Since the length is in feet and the width is in inches, we need to convert them to the same unit. Let's convert the width to feet:

* There are 12 inches in a foot, so 15 inches is equal to 15/12 = 1.25 feet.

2. Calculate Area:

* The area of a rectangle is calculated by multiplying length by width:

* Area = Length * Width

* Area = 10 feet * 1.25 feet

* Area = 12.5 square feet

Therefore, the area of the rectangle is 12.5 square feet.
