Step-by-step explanation:
Area of quadrilateral = (½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices.
One thing you must see that the heights of perpendicular drawn both be equal because from the figure it's clear that that both height will perpendicular to each and also diagonal is common also angle fromed in both the triangles is 90°. So both triangles are congruent to each other like
this in both the triangles AB=BC from the figure , also after construction 90° is common and diagonal is common so from SAS congruency both triangles are congruent so so the height after construction will be equal and so both heights will be 6 cm each.
Area of quadrilateral is= 1/2×11×(6+6) cm²
=1/2×11×12 cm²
=66 cm²
