Answer 2

The pentagon is enlarged using a scale factor of 5/2 "

you multiply each side by 5/2 or 2.5 to get 6*(5/2) = 6*(2.5) = 15

each side is now 15 cm long. This is not the answer as it's just an example

Answer 4

each side is 20 cm

there are 5 sides (this is a pentagon)

each side is congruent or equal to one another (it's a regular polygon)
