## NCERT Solutions for Class 10 Maths Chapter 7 Coordinate Geometry Ex 7.3

**Question 1.**

**Find the area of the triangle whose vertices are:**

**(i)** (2, 3), (-1, 0), (2, -4)

**(ii)** (-5, -1), (3, -5), (5, 2)

**Solution:**

**Question 2.**

**In each of the following find the value of ‘k’ for which the points are collinear.**

**(i)** (7, -2), (5, 1), (3, k)

**(ii)** (8, 1), (k, -4), (2, -5)

**Solution:**

**(i)** Since the given points are collinear, the area of the triangle formed by them must be 0, i.e.,

**
(ii)** Since the given points are collinear, the area of the triangle formed by them must be 0, i.e.,

**Question 3.**

**Find the area of the triangle formed by joining the mid-points of the sides of the triangle whose vertices are (0, -1), (2, 1) and (0, 3). Find the ratio of this area to the area of the given triangle.**

**Solution:**
