the area of parallelogram with base 8.6cm and height 6.8cm is the same as a rhombus with length of one diagonal 7.31cm .Find the length of other diagonal of the rhombus

area of parallelogram = base multiplied by height= 8.6*6.8=58.48cm2
let the other diagonal be x cm
given
area of rhombus= area of parallelogram
1/2 * product of diagonals= base * height
1/2* 7.31*x= 8.6*6.8
x=58.48*2/7.31
x=4*2=8
So, the length of other diagonal is 8 cm
