AB = BC=CD = DA = 13 CM
BD = 10 CM
OA = 1/2 AC
OB = 1/2 BD = 5 CM,
OA^2+ OB^2 = AB^2
OA = √(144) = 12 CM
LENGTH OF OTHER DIAGONAL IS 12 CM
BD = 10 CM
OA = 1/2 AC
OB = 1/2 BD = 5 CM,
OA^2+ OB^2 = AB^2
OA = √(144) = 12 CM
LENGTH OF OTHER DIAGONAL IS 12 CM

area =base ×height
so area =13×10 =130
area van also calculated by 1/2 ×d1×d2
so we can say ... 1/2 ×10×d2=130
d2=130×2/10×1
=26cm ^2
so area =13×10 =130
area van also calculated by 1/2 ×d1×d2
so we can say ... 1/2 ×10×d2=130
d2=130×2/10×1
=26cm ^2
