Question

A triangle ABC has been enlarged by scale factor m = 2.5 to the triangle A' B' C'. Calculate : the length of C' A' if CA = 4 cm. 

Answer 1

Given that ABC has been enlarged by scale factor m = 2.5 to the triangle A' B' C' 

If CA = 4 cm

So, CA (2.5) = C'A'

`=>` (4) (2.5) = C'A'

`=>` C'A' = 10 cm
