Answer: The actual area of the park = 24 square miles.
Explanation:
Given : 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 mile.
i.e. i inch on map = 1 actual mile
so, 4 inches on map = 4 actual miles
6 inches on map = 6 actual miles
Area of rectangle = length x breadth
⇒ Area of rectangle = 6 x 4 square miles
= 24 square miles.
Hence, the actual area of the park = 24 square miles.
