More important, what is the question? Four different lengths do not define a rectangle.
The side lengths of a quadrilateral do not uniquely identify the shape, because a quadrilateral is not a rigid shape. It can be flexed so that its area can be varied without changing the side lengths. As an example, consider a rectangle. It can be flexed into a parallelogram which can be made so thin that its area can be made smaller than any given value. Whereas a general quadrilateral may have a residual triangle that cannot be removed, there is a huge range of values for the area.

15ft x 9ft = 135 square feet.
12 * 9 = 108 square feet = 12 square yards
It is 1699 = 1296 cubic feet

Hmm - well, for one thing, it would wouldn't be referred to as area, as area represents a two dimensional measurement. What you're naming is a four dimensional measurement, so we would probably refer to it as hypervolume. The principal behind measuring hypervolume would be the same as that of measuring the area of a rectangle or the volume of a box. Simply multiply it's side lengths together: 29ft * 17ft * 15ft * 9ft = 66555ft4

12.54 square meters.
15ft x 9ft = 135 square feet.

135 square feet. Just multiply length by width - the answer is the square footage.
Well you convert the yards into feet. That would be 9ft x 15ft. That equals 135 feet2
135 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
15x9 = 135 squared feet
how many square yards of carpet will they need for a dining room9ft and 12ft, a hall 3ft and 6ft, a living room 12f and 15ft
12 * 9 = 108 square feet = 12 square yards
