Question

if the area of a rhombus is 369 square metre and one of the diagonal is 18 metre long then find the other diagonal​

Answer 1

Answer:

area of the rhombus  = 369m²

are of a bhombus is half of product of diagonals.

ie area of rhombus = (1/2)(d1×d2)    where d1 and d2 are diagonals

 here d1 = 18m

(1/2)(18m×d2) = 369m²

        18 × d2   = 369×2

                 d2   = (369×2)/18

                  d2   = 738 / 18

                    d2 = 41m

41 is the length of the other diagonal.
