If the drawing of your octagon (or whatever) has been separated into triangles, and one triangle's area<span> is labeled, then you do not need to know the apothem. Just take the </span>area<span> of that one triangle, and multiply by the number of sides in the original </span>polygon<span>.</span>
It would be the one where measurement 1m is the side of the triangle, measurement 0.75m is the bottom of the triangle, and measurement 2m is the long side of the rectangle
First you take 29 over 185 and x over 100 and you cross multiply which gives you 185x is equal to 2900 then you take 185x and 2900 and you divide both by 185 and you end up with x equals 15.68 or 15.68% which is letter B
