Question

Mr. jovanovski is having wood flooring put in his rectangular living room. the area of the room is 234 square feet. the length of the room is 18 feet. what is the width, in feet, of the room?

Answer 1

The area of a rectangle is L * W where L is the length and W is the width  
Hence it follows that L * B = 234 
But Length, L, = 18 
So we have 18 * W = 234
 So W = 234/18 = 13 
Hence the width of the room is 13 feet

Answer 2

By definition the area of a rectangle is:
 A = l * w
 Where,
 l: long
 w: width
 So we have to clear the width:
 w = A / l
 Substituting the values:
 w = (234) / (18) = 13
 w = 13 feets
 answer
 the width, in feet, of the room is 13
