ddie measured a petting zoo and made a scale drawing. He used the scale 5 centimeters : 2 meters. If the goat pen is 45 centimeters in the drawing, how long is the actual pen

Answer 1

Change the centimeters to meters first. 5 cm/100cm=.05 meters, 45cm/100cm=.45m

Then you set up a ratio of:.05/2=.45/x. I would then cross multipy .05x=.90, .90/.05=18 meters.
