Question

A rectangular family room  has 204 square feet of floor space  if it's length is 17 feet how many feet wide is it

Answer 1

204 square feet of floor space means the area is 204 square feet.  Area is equal to the length (l) times the width (w) or A = l * w.  

Since you know A equals 204 ft² and l equals 17 ft, you just have to solve for w.

204 ft²= 17 ft * w ft

Divide both sides by 17 to get 204 ft²/17 ft = w ft

Thus w = 12 ft.
