Key Idea Use $p\to q$ then inverse of it is
$\sim p\to \sim q$ and contrapositive is $\sim q\to \sim p$
The inverse of the given statement: “If two triangles are not congruent, then their areas are not equal.”
$\therefore$ The contrapositive of the inverse of the given statement : If areas of two triangles are equal, then are congruent.
