I'm not sure what you're asking for, but I think this should be the answer:
In he number 913,256, 913 comprises the THOUSANDS period.

Your answer would be 0.3m.
This is because an isosceles triangle has two sides of the same length, usually on either side above the base, which means we can first do 1 - 0.4 = 0.6m to get the total amount that the two sides add up to, and then 0.6 ÷ 2 = 0.3 to get how long each side is.
I hope this helps!
