Answer:
Option (b) is correct.
The approximate area of this park is about 55 mi² to 65 mi².
Step-by-step explanation:
Given : A grid with Each square on the grid represents 1 mi². and a park is constructed on it.
We have to determine the approximate area of this park.
We first find the area of grid and then subtract the uncovered square that are not covered in park area.
Length of square grid is 10 mi and breadth is 8 mi.
So, area of square grid = 10 × 8 = 80 mi²
Number of uncovered squares that are not covered in park area = 9 squares
So Area of uncovered squares = 9 mi²
Maximum area of park is (80 - 9) = 71 mi²
Also, Area of partially covered squares = 21 mi²
So, Minimum area of park is (80-30) = 50 mi²
Since, area of park lies in between 50 to 71
So , from given options only (b) satisfies the approximate area of this park.
Thus, the approximate area of this park is about 55 mi² to 65 mi².
