Skipping some sectors will come back to bite me?

Hey guys, so I'm working through this book and so far I've learnt about squares, triangles and circles. Now the book is going to go into the weird shapes such as rhombus', trapezoids ect, I'm kinda bored of this stuff already so I'm just wondering if skipping it will come back to haunt me later on?

My goal at the moment is to learn calculus.

I would say you can skip the sections for areas of geometric shapes unless you would need to derive those equations.

I say if you expect to do calculus (especially integral calculus and differential geometry) then you are expected to have a very firm grasp of geometry and mensuration. So no, don't skip them.
