The area of quadrilateral is 133 sq.cm.
Since we have given that
The diagonal of a quadrilateral intersect each other at right angle.
So, the quadrilateral becomes "Rhombus".
Length of first diagonal = 14 cm
Length of another diagonal = 19 cm
So, the area of rhombus becomes
=1/2×d1×d2
=1/2×14×19
=7×19
=133cm^2
