Area of the park is represented by the grey color shaded area which is about 20 squares. Since, we know area of 2 squares = 5000, total area of park is 5000 * 10 = ~ 50,000. Therefore, option B (45,000).

There are 30 little squares in total. Since two little squares have an area 5.000, 30 little squares have an area of 75.000. Hence answer D.

The area of pond covers 2 squares which is 5000 yards. The total area consists of 30 squares. Hence the total area is approximately equals to 75000. Ans D

The answer choices were spread out enough, so I just counted how many squares there were. I got roughly 18 squares. So for easier math I rounded up to 20 and did 20*2500=50,000. Closest answer is B. Took me about 1:15min.

Given: Area of pond=5,000 square yards Question stem: Approximated area of park(Shaded regiongrey in color)= Area of rectangular grid Area of Unshaded region? Observations: 1. Total nos. of squares in the rectangular grid=No of vertical squares*No of horizontal squares=6*5=30 2. Pond(depicted in black) covers 2 squares approx. Let the side of each smallest identical square be 'a' yard. So, area of pond=\(a^2+a^2=2a^2=5000\) Or, area of each square=\(a^2=2500\) Or, \(a=\sqrt{2500}=50 yards\) Now, area of rectangular grid=no of squares*area of one square=30*2500=75,000 sq. yards Refer the enclosed diagram, we have 7 nos(approx.) of full squares, 6 nos(approx.) of halfsquares, and 8 nos negligible areas(may be approximated to one square). So, area of unshaded region=\(7a^2+6*(\frac{a^2}{2})+a^2=7*2500+3*2500+2500=17500+7500+2500=27500\) sq. yards Hence the approximated area of park=(7500027500)sq. yards=47500 sq. yards Among the answer options, 45000 sq. yards is the closest. Ans. (B)

So total area of grid = \(30*2500 = 75000\) In the bottom right corner, 5 squares are not shaded. REMEMBER: WE NEED TO FIND OUT THE AREA OF THE PARK AND NOT OF THE GRIDI do this question by subtracting the approximate area of the non shaded portion from 75000 (the area of the grid) Fully shaded/ partly shaded area = 25*2500 = 62500 The only Options left are A and B. To rule out A, \(x*2500 = 30000\) \(x= 12\) This means that 12 is the area of the park in terms of the squares in the grid i.e. 12 squares. This seems very less because around 10 squares are fully covered (Including the pond) and a lot partly which would add up to more than 12. Thus B is the best answer choice.
