**Distance Formula CBSE NCERT solutions Chapter 7 Exercise 7.1 Question 2**

**2.** Find the distance between the points **(0, 0)** and** (36, 15).** Also, find the distance between towns **A** and **B** if town **B** is located at 36 km east and15 km north of town **A**.

**Solution:**

Applying **Distance Formula** to find distance between points **(0, 0) and (36, 15), **we get

**d =**

Town **B** is located at **36 km** east and**15 km** north of town **A**. So, the location of town** A** and **B** can be shown as:

Clearly, the coordinates of point **A** are **(0, 0)** and coordinates of point** B** are **(36, 15)**.

Note that coordinates of points **A** and **B** can vary according to the description of the problem but the distance between them would be constant.

To find the distance between them, we use **Distance formula**:

**d =** Km
