Question

A map that was createdusing a scale of 1 inch : 3 milesshows a lake with an area of18 square inches. What is theactual area of the lake?___ square miles

Answer 1

For this case we have the following scale given: 1 inch: 3 miles

We know that a lake have an area of 18 in^2 and we want to find the actual area of the lake in miles^2

Since we have the conversion factor we can use this and we got::

`18in^2\cdot((3mi)^2)/((1in)^2)=18in^2\cdot(9mi^2)/(1in^2)=162mi^2`

So for this case we can conclude that the answer would be 162 mi^2
