Byron placed bricks in a row to make a border that was 16.9 feet long. each brick is 1.3 feet long. how many bricks are in the border? a. 13 b. 12 c. 1.3 d. 1.24

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
