Question

If the diagonals of the rhombus are in the ratio 4:7 and the area is 504sqcm find the length of the diagonals​

Answer 1

(i) Using distance formula, we have

AB=√(6-3)²+(4-1)² = √(3)² + (3) ²

= √9+9 = √18 = 3√2 units

BC √(8-6)² + (6-4)² = √(2)²+(2)²

= √4+4 √8 = 2√2 units

AC = √(8-3)² + (6-1)² = √(5)² + (5)²

= √25+ 25 = √50 = 5√2 units

AB+ BC = 3√2+2√2 = 5√2 = AC

. A, B and C are collinear.
