Question

A map of a rectangular park has a length of 4 inches and a width of 6 inches. It uses a scale of 1 inch for every 30 miles.

What is the actual area of the park? Show how you know.

The map needs to be reproduced at a different scale so that it has an area of 6 square inches and can fit in a brochure. At what scale should the map be reproduced so that it fits on the brochure? Show your reasoning.

Answer 1

Explanation:

L = 4 in real life = 4*30 =120 miles

W=6 in real life =6*30=180 miles

actual area = 120*180 = 21600sq miles

to fit into a 6sq in paper it'll need to shrink to 2x3 inches, 1/2 of what it was before, so the scale becomes 1" for every 60miles.
