Question

what is the area of a octagon is the h=20.52 and the w=17

Answer 1

so there is octagon what sign that this polygon has 8 sides and what sign again too that this polygon can being separated in 8 triangles equales
so you need just calcule area of one triangle and this multiplie by 8 and will get the area of octagon

area of one triangle will be =(17*20,52)/2 =17*10,26 =174,42
so than area of octagon will be 8*174,42=1395,36

hope so much that is understandably sure right

good luck
