vitfil [10]

Answer:

The length of each side of the square park is 2,400 ft

Step-by-step explanation:

we know that

The scale is $\frac{1}{200}\frac{in}{ft}$

step 1

Remember that

1 ft=12 in

The length of each side on the map is 1 ft

Convert ft to in

1 ft=1(12)=12 in

step 2

Find the length of each side of the square park

using proportion

Let

x ----> the actual length of each side of the square park

$\frac{1}{200}\frac{in}{ft}=\frac{12}{x}\frac{in}{ft}\\\\x=200*12\\\\x=2,400\ ft$
