Please help! Find the area of the regular polygon!

Special right triangles only!

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a

you can use a^2+ b^2=c^2

um is there supposed to be a picture?
