Calculate the area of a rhombus if one of its diagonal is 20 dm and the other is 17 dm.
May 1, 2021 | education
| The diagonals of the rhombus at the intersection point are halved and divide the rhombus into four equal triangles.
Then AO = AC / 2 = 20/2 = 10 dm.
ОВ = ВД / 2 = 17/2 = 8.5 dm.
Determine the area of the triangle AOB.
Saov = AO * ВO / 2 = 10 * 8.5 / 2 = 42.5 dm2.
Then Savsd = 4 * Saov = 4 * 42.5 = 170 dm2.
Answer: The area of the rhombus is 170 dm2.
