( PLEASE PLEASE SAID THANKS THIS ANSWER I WANT IT FOR GETTING A RANK PLEASE )

   you know Altitude (height) and side s the formula is: area = height × s.

If you know the length of one side s and the measure of one angle the formula is: area = s2 sin(∠A) = s2 sin(∠B)

If you know the lengths of the diagonals the formula is: area = (d1 × d2)2.

Answer is 0.87
