Solution
Consider 1 triangle formed when both diagonals are drawn.
side ^ 2 = (1/2 diagonal 1)^2 + (1/2 diagonal 2)^2
400 = 144 + (1/2 diag 2) ^2
=> diag 2 = 32.
diag 1 = 24.
Area = 24 x 16 = 384.
side ^ 2 = (1/2 diagonal 1)^2 + (1/2 diagonal 2)^2
400 = 144 + (1/2 diag 2) ^2
=> diag 2 = 32.
diag 1 = 24.
Area = 24 x 16 = 384.
