Question

Compare the original figure to the enlarged figure.

A small rectangle has a length of 3.25 and width of 1.5. A larger rectangle has a length of 6.5 and width of 3.

Which ratios can be used to find the scale factor? Check all that apply.
Scale factor = StartFraction enlarged over original EndFraction = StartFraction 6.5 over 3.25 EndFraction
Scale factor = StartFraction enlarged over original EndFraction = StartFraction 3.25 over 6.5 EndFraction
Scale factor = StartFraction enlarged over original EndFraction = StartFraction 3 over 1.5 EndFraction
Scale factor = StartFraction enlarged over original EndFraction = StartFraction 1.5 over 3 EndFraction
Scale factor = StartFraction enlarged over original EndFraction = StartFraction 1.5 over 3.25 EndFraction

Answer 1

a and c

Explanation:

Answer 2

All the options are correct apart from the last one

Explanation:

• Scale factor is the ratio of corresponding sides

Scale factor = 6.5 / 3.25

• Yes

Scale factor = 3.25 / 6.5

• Yes

Scale factor = 3 / 1.5

• Yes

Scale factor = 1.5 /3

• Yes

Scale factor = 1.5 / 3.25

• No, as it is the ratio of sides of the same rectangle
