The diagonals of the convex quadrilateral ABCD are mutually perpendicular and their lengths are 12.4 cm and 15 cm. Find its area.
The area of a convex quadrilateral is equal to the product of the lengths of its diagonals by the sine of the angle between them.
Savsd = АС * ВD * SinАВ = 12.4 * 15 * Sin90 = 186 cm2.
Answer: The area of the quadrangle is 186 cm2.
