Question

the length of two sides of parallelogram 12 m and 8m . If the smallest diagonal is 10 m.Find the other diagonal length

Answer 1

let the other diagonal be d cm.
Given,
two sides=12m and 8m
smallest diagonal=10m
then,
12×10=8×d [each=area of ||gm]
120=8d
d=15m
therefore,the other diagonal is 15m(Ans)

Answer 2

The length of 2nd diagonal is 17.77m if I had not committed any calculation mistake.... :)
hope it helps you....
