-
- According to parallelogram law:-The sum of the squares of a sides is equal to the sum of the squares of the diagonal.
so,
12^2+12^2+14^2+14^2=d^2+16^2 =>d=20.59. - 10 years agoHelpfull: Yes(13) No(0)
- Parallelogram law,
2*(side1)^2+2*(side2)^2=(d1)^2+(d2)^2
2*(12)^2+2*(14)^2=16^2+x^2
by solving x=20.59 - 10 years agoHelpfull: Yes(5) No(0)
- length of second diagonal= 20.59cm

- parallelogram property :
2*(side1^2)+2(side2^2)=diagonal1^2 +diagonal2^2
2*12*12+2*14*14=16*16+x^2
x=20.59 - 10 years agoHelpfull: Yes(2) No(1)
- ans =19.80cm
