Hardy was given the scale drawing of the enlargement to find the scale factor and missing lengths. His work is shown below. Side A corresponds with 1.5, side B corresponds with 4, and a side with length 30 corresponds with a side with length 6.
1. Scale factor = StartFraction Scale drawing dimension over original dimension EndFraction = StartFraction 30 over 6 EndFraction = 5. Side A = 1.5 + 5 + 6.5. Side B = 4 + 5 = 9.
Analyze Hardy’s work to determine if he is correct. If he is incorrect, what is his error?
Yes. Hardy is correct.
No. Hardy should have used the ratio of the original to the scale drawing to find the scale factor.
No. Hardy should have multiplied by the scale factor to find the missing length.
No. Hardy should have divided by the scale factor to find the missing length.
