a.
Explanation of Solution
Given information:The given figure is.
In quadrilateral
So,
(quadrilateral in which opposite sides are equal is a parallelogram)
LN is a diagonal in parallelogram TLMN and diagonal of a parallelogram divides it into two congruent triangles.
Therefore,
Similarly,
So,
b.
To calculate: Area of
b.
