What is the area of a triangle that has a base of 15 yards and a height of 11 yards? 330 yd 2 165 yd 2 82.5 yd 2 41.25 yd 2

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
