Gretchen is using an overhead projector to enlarge a drawing so she can make a poster. The original drawing measures 60 mm wide by 80 mm high. She moves the projector so that the width of the projected image is 300 mm. If the original drawing and the projected image are similar figures, what will be the height of the projected image?

A. 225mm

B. 440mm

C.180mm

D. 400mm

Answers

(D) this is a ratio problem. Take the new width over the old width to get the ratio. so 300/60 is 5. then multiply that by the old height to get the new height. 80 X 5 which is 400.
