The rhombus has a side 22 cm and one diagonal 35 cm long. Calculate its area.

Final Answer:

S =  466.6 cm2

Step-by-step explanation:

a=22 cm u=35 cm  Δ ABC: a=22 a=22 u=35  s=2a+a+u=222+22+35=279=39.5 cm S1=s (sa) (sa) (su)=39.5 (39.522) (39.522) (39.535)233.3151 cm2  S=2 S1=2 233.3151=466.6 cm2
