Asked by Naya

A rectangular room is 3m longer than it is wide.
It costs 364 pounds to carpet the room. Carpet costs 16 pounds per square metre.
How wide is the room?
Answered by Steve
w(w+3)*16 = 364
now just solve for w.
Answered by Henry
Area = 364/16 = 22.75 m^2

Width = W meters.
Length = W+3 meters.

Area = (W+3) * W = 22.75
W^2 + 3W - 22.75 = 0
Use Quadratic Formula:
W = 3.5 meters = Width.
