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 30 Miles. What
andre [41]

Answer:

Step-by-step explanation:

Dimensions of the rectangular park = 4 inches by 6 inches

Since scale factor = \frac{\text{Dimensions of the park on map}}{\text{Dimensions of the original park}} = \frac{1}{30}

\frac{4}{\text{Length of the original park}}=\frac{1}{30}

Length of the original park = 120 miles

Similarly, width of the park = 180 miles

Area of the park = Length × Width

                           = 120 × 180

                           = 21600 square miles

Therefore, area of the original park is 21600 square miles.

Formula for the ratio of area of the park on map and original park is,

\frac{\text{Area of the park on map}}{\text{Area of the original park}}=(\text{Scale factor})^2

\frac{6}{21600}=(\text{Scale factor})^2

Scale factor = \sqrt{\frac{1}{3600}}

                    = \frac{1}{60}

Scale factor to reproduce the map so that it fits in the brochure will be 1 inch for every 60 miles.

1/3x = -4 + 10/3

1/3x = -2/3

x = -2/3 · 3
