Find the area of a regular hexagon with an apothem 10.4 yards long and a side 12 yards long. Round your answer to the nearest tenth and show your work.

The hexagon has 6 congruent triangles that look like this |dw:1401260973427:dw|

jimthompson5910 (jim_thompson5910):

use the formula A = (b*h)/2 to find the area of 1 triangle then multiply by 6 to get the total area of the hexagon

OpenStudy (anonymous):

\[a=bh \div 2\]

jimthompson5910 (jim_thompson5910):

yes use that

OpenStudy (anonymous):

\[a=12\times10.4\div2\]

OpenStudy (anonymous):

\[a=62.4\times6\]

OpenStudy (anonymous):

\[A=374.4\]

is that right?

jimthompson5910 (jim_thompson5910):
