The side length of the diamond is 35 cm, and the length of the diagonal is 56 cm. Calculate the height and length of the second diagonal.

Correct answer:

v =  16.8 cm
u =  42 cm

Step-by-step explanation:

S1=S2 21av=21u1u2 2135v=2156u 35v=56u a2=(u1/2)2+(u2/2)2 352=(56/2)2+(u/2)2 v=4156u/(35)=16.8 cm 
u=4 352562=42 cm
