Step-by-step explanation: Since the length to width ratio is 3 to 1, to find length, you would multiply the width by 3. So, the width of 33 would mean the length is 99.
Since we know the length (L) to width (W) ratio is 3 to 1, we can put the ratio in the form of a fraction and solve for the unknown length (L’).
Therefore we have L/W = 3/1 = L’/33
Moving the width of 33 to the other side of the equation, we have 3/1 * 33 = L’
99/1 = L’
99 = L’
Therefore the length L’ should be 99cm if the width is 33cm.
