we know the diagonals make triangle total triangle are 4
the diagonal length is 20 cm they are bisecting each other at a point which means the half will be 10cm and the diagonals make a 90 degree angle which means we can take 10 cm as hieght and base of triangle
area of triagle = 1/2 x 10 x 10 = 50
total triangles = 4
4x50 = 200
