Answer» Question : The area of rhombus is 380cm² and one of the diagonal is 19 cm. FIND the other diagonal? ANSWER : $\sf\pink{Given:}$ Area of rhombus is 380 cm². One of the diagonal is 19 cm . $\sf\pinl{To\:find:}$ other diagonal ? Explanation : let the other diagonal be "d" Area of rhombus = ½ × diagonal 1 × diagonal 2 $\longrightarrow\sf{380 = \dfrac{1}{2}\times 19\times d}$ $\longrightarrow\sf{380 = \dfrac{19}{2}\times d}$ $\longrightarrow\sf{380\times \dfrac{2}{19} = d}$ $\longrightarrow\sf{20\times 2 = d}$ $\longrightarrow\sf{40 = d}$ THEREFORE the other diagonal is 40 cm .
