Question

Triangle EFG is dilated by a scale factor of 1/4 ​ to form triangle E'F'G'. Side E'F' measures 12.512.5. What is the measure of side EF?

Answer 1

Answer: 3.125

Explanation:

Given

Triangle is dilated by a factor of
`(1)/(4)` i.e. each side multiplies to 0.25.

Side E'F' becomes 0.25 times the original length

`\Rightarrow E'F'=(1)/(4)* 12.5=3.125`
