Need help on spacing supports for metal trunking please

Evening people, my first time posting here.
Apologies if it isn't in the right category.

I am currently writing up my portfolio/NVQ for my apprenticeship and I am looking at table D4 in the OSG. Trying to find 100mm x 100mm metal trunking on column one but they are listed as cross sectional area. How do I work out which row 100mm x 100mm trunking will fall under in column number 1?

Much appreciated if anyone could help!

Calaculate the cross-sectional area of your square trunking. It is one of the easier shapes to compute!

X SEC. AREA = 100 x 100 = 10,000 sq. millipedes. so support spacing is 3m or 10ft. in english. sssimpless.
