P, Q, R are three villages PQ=10 km , QR=8km and PR is 4km are connecting roads. Using a scale of one cm to represent one km ,locate the relative positions of the three villages

1 answer

To locate the relative positions of villages P, Q, and R, we can represent the distances on a piece of paper using the given scale of 1 cm = 1 km. The distances between the villages are:

  • PQ = 10 km (10 cm)
  • QR = 8 km (8 cm)
  • PR = 4 km (4 cm)

Here’s how to plot the points step-by-step:

  1. Draw Line PQ:

    • Start by drawing a horizontal line segment representing PQ. Since PQ is 10 km, draw a line that is 10 cm long. Label the endpoints as P and Q.
  2. Locate Point R:

    • You know that PR = 4 km (4 cm) and QR = 8 km (8 cm). From point P, you will measure 4 cm towards the direction where R might be placed.
    • From point Q, you will measure 8 cm in a suitable direction for point R.
  3. Finding R:

    • Since P and Q are fixed points, you can use the distances from both points to create circles where point R could be located.
    • Draw a circle centered at P with a radius of 4 cm (this represents PR).
    • Draw another circle centered at Q with a radius of 8 cm (this represents QR).
    • The point where the two circles intersect is point R.
  4. Label the points:

    • After finding the intersection point, label it R.

You should find that R is positioned relative somewhere in the space according to the distances given. Make sure to maintain the correct scale and angles while drawing for accuracy.

Summary of the steps:

  • Draw PQ (10 cm)
  • Draw a circle at P (4 cm radius)
  • Draw a circle at Q (8 cm radius)
  • Intersecting point = R

This will give you the relative positions of villages P, Q, and R on your paper.
