**Section Formula CBSE NCERT Solutions Chapter 7 Exercise 7.2 Question 10**

**10.** Find the area of a rhombus if its vertices are (3, 0), (4, 5), (-1, 4) and (-2, -1) taken in order. **{Hint: Area of a rhombus = (product of its diagonals)}**

**Solution:**

**Let A = (3, 0), B = (4, 5), C =(-1, 4) and D = (-2, -1)**

**Using Distance Formula to find length of diagonal AC, we get**

**Using Distance Formula to find length of diagonal BD, we get**

**Area of rhombus =** **(product of its diagonals)**
