Answer by srinivas.g(540) (Show Source): You can put this solution on YOUR website!
perimeter (4s)= 20 cm
each side (s)= 20/4 =5 cm
diagonal = 8 cm
half of diagonal = 4 cm
half of other diagonal = sqrt(5^2 -4^2)
= sqrt(25-16)
=sqrt(9)
= 3 cm
full length of other diagonal = 6 cm
area = 0.5* diagonal 1 *diagonal 2
= 0.5*8*6
= 24 square centimeters
