The area of rhombus is given as 75sq.cm with one diagonal as 5cm.
Let dcm be the length of the other diagonal, then,
75=12×5×d
d=75×25
d=30cm
Therefore, the other diagonal is 30cm long.
Find the area of a rhombus whose side is 5 cm and whose altitude is 4.8 cm. If one of its diagonal is 8 cm long, find the length of the other diagonal.
