Find the area of this shape.

Step-by-step explanation:

Firat triangle has a=4cm and b=a and P1=a*b/2=4*4/2=8cm^2

First parallelogram has h=4cm (from first triangle) and a=5.7cm

P2=a*h=22.8cm^2

Big triangle has h=4 and a=5.7+4=9.7

P3=a*h/2=9.7*4/2=19.4

And 4th triangle has the same are lik the first one, P4=8.

P=8+22.8+19.4+8=58.2cm^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.
