Basil was shown this enlargement, and he was asked to find the perimeter of the enlarged shape. His work is shown below.

A shape has side lengths 2, 2, 6, 4, 6. A larger shape has corresponding sides, A, A, 24, B, 24.
Figures not drawn to scale.

Basil’s Work
Scale factor
StartFraction 24 over 6 EndFraction = 4
Side A
4 times 2 = 8
Side B
4 times 4 = 16
Perimeter
24 + 16 + 8 + 8 = 56

Where, if any, did Basil first make a mistake in his work?
Basil made a mistake finding the scale factor.
Basil made a mistake when finding the length of either side A or side B.
Basil made a mistake finding the perimeter.
Basil did not make any mistakes in his work.
