Let s be the length of a side of the hexagon and let h be the the apothem 6(1/2sh) it the area of 3sh.
About 10.39 square feet.The formula is A = 3/2 (sqrt 3) s2(this is about 2.598 times the side length squared)
Easy. Since the side is the base and the apothem is the height of the triangle, multiply them and divide by two to get the area of the triangle. 3 * 3.46 = 10.38 /2 = 5.19. Then multiply by 6 to get the area of the hexagon. 5.19 * 6 = 31.14. You multiply by 6 because you can fit 6 regular triangles in a regular hexagon. We've already found the area of one regular triangle in the hexagon.
yes.
area = length x width = 20 x 15 = 300 sq cm
