Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFArea of Rhombus = 1/2 × product of diagonals
⇒ 720 = 1/2 × product of diagonals
⇒ Product of diagonals = 1440
(Side of rhombus)2 = (half of one diagonal)2 + (half of the other diagonal)2
⇒ (One diagonal)2 + (Other diagonal)2 = 41 × 41 × 4
(Sum of two diagonal)2 = (One diagonal)2 + (other diagonal)2 + 2 × product of diagonals
⇒ (Sum of two diagonal)2 = 6724 + 2880 = 9604
∴ Sum of two diagonal = 98cmLast updated on Jul 15, 2025
