Question

a map of a rectangle park has the length of 4inches and a with of 6 inches. It uses a scale of 1 inch every 30 miles. What is the area of the park

Answer 1

Answer:

720 mi²

Step-by-step explanation:

The map has a scale of 1 in: 30 mi, meaning that for every inch you see on the map, in the real-life location, it will measure 30 miles. So we can find the area of the park on the map and then turn it into miles using the scale:

Area of a rectangle:

$A=bh$

Replace the known values:

$A=(4)(6)\\ A=24$

The area on the map is 24 mi², we can turn it to miles using the scale by multiplying our result with 30:

$A=(24)(30)\\ A=720$

And last but not least, don't forget to put the unit!
