Perimeter=200cm=4*side
Hence Side=50cm
Diagonal1=80cm
Diagonal2=?
(Side)²=(Diagonal1/2)²+(Diagonal2/2)²
(Diagonal2/2)²=(50)²-(40)²
Diagonal2=60cm
Area = .5*diagonal1*diagonal2
1/2*80*60
40*60
2400cm²
Hence Side=50cm
Diagonal1=80cm
Diagonal2=?
(Side)²=(Diagonal1/2)²+(Diagonal2/2)²
(Diagonal2/2)²=(50)²-(40)²
Diagonal2=60cm
Area = .5*diagonal1*diagonal2
1/2*80*60
40*60
2400cm²
