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)
