Answer:

16.33 units.

Step-by-step explanation:

Given are the vertices of triangle BCD as B(–3, 3), C(3, 5), and D(–1, 0).

Side CD = 6.403   DE= 3.606   EC = 6.325

using distance formula between two coordinates.

Distance between (x1,y1) and (x2,y2)

= \sqrt{(x_2-x_1)^2 +(y_2-y_1)^2}

Perimeter = sum of all sides

= 6.403+3.606+6.325

= 16.332

Kim is drawing a map of the different schools in her school district. she knows that her middle school is 10.6 miles away from t
romanna [79]

The distance between the two schools on the map is (C) 4.2 inches.

<h3>What is the distance?</h3>
  • Distance is a numerical measurement of the distance between two objects or places.
  • The distance can refer to a physical length or an estimate based on other criteria in physics or common usage.
  • The distance between two points A and B is commonly expressed as |AB|.

To find the distance:

On the map,2 inches represents 5 miles.

Thus, we can write:

  • 2 miles = 2 inches
  • 1 mile = 2/5 inches ..... (1)

Since the actual distance between the two schools is 10.6 miles.

Multiplying both sides by 10.6 in equation (1).

  • 10.6 miles = 10.6 × 2/5 = 21.2/5 = 4.24 inches.

Therefore, the distance between the two schools on the map is (C) 4.2 inches.
