Alex simplified the expression 7 + (3 times 1.4) + 5 + 2 + (5 times 1.4) to find the area of the figure on the grid. On a coordinate plane, a figure has side lengths of 7, (3 times 1.4), 5, 2, (5 times 1.4).

What error did Alex make?
He found the perimeter of the figure instead of the area.
He added the lengths of the lines creating the indentation instead of subtracting them.
He used 5 times 1.4 and 3 times 1.4 as the length of each diagonal line instead of 5 and 3.
He added the five lengths together instead of multiplying them.

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.
