Answer:To calculate the length and width of the original figure with a scale factor of 50%, you need to reverse the scaling by multiplying the new dimensions by 100% / 50% = 2.
So if the new length is L, the original length would be L * 2 = 2L. Similarly, if the new width is W, the original width would be W * 2 = 2W.
Step-by-step explanation:here's a step-by-step explanation:
Identify the new length (L) and new width (W) of the figure.
Multiply the new length by a factor of 2 to find the original length: 2L = L * 2
Multiply the new width by a factor of 2 to find the original width: 2W = W * 2
The original length is 2L and the original width is 2W.
Note: This process works for any scale factor, not just 50%. To find the original dimensions, simply multiply the new dimensions by 100% / the scale factor.
