Diamond diagonals

Find the diamond diagonal's lengths if the area is 156 cm2 and side is 13 cm long.

Correct result:

u =  21.6333 cm
v =  14.4222 cm

Solution:


Our quadratic equation calculator calculates it.

v=2 S/u=2 156/21.6333=4 1314.4222=14.4222 cm  v=u2  S2=u v2=21.6333 14.42222=156 cm2 a2=(u/2)2+(v/2)2=(21.6333/2)2+(14.4222/2)2=13 cm
