Diagonals in the diamond

The length of one diagonal in diamond is 24 cm greater than the length of the second diagonal and diamond area is 50 m2. Determine the sizes of the diagonals.

Correct answer:

u1 =  1012.07 cm
u2 =  988.07 cm

Step-by-step explanation:

u2=u124 S=u1u22=u1(u124)2=50 m2=500000 cm2 2S=u1224u1 u224u1000000=0  a=1;b=24;c=1000000 D=b24ac=24241(1000000)=4000576 D>0  u1,2=b±D2a=24±40005762=24±8625092 u1,2=12±1000.0719974082 u1=1012.0719974082 u2=988.07199740819   Factored form of the equation:  (u1012.0719974082)(u+988.07199740819)=0  u>0 u1=1012.07 cm
u2=u124=988.07 cm
