first, we do
squaer is legnth 6 so base =6
10-6=4
the rectangle is 2 by 4
base=4
square is 6 by 6
the rectangle is 4 by 2
split the triangles up
area of triangle=1/2base times height
rectangle triangle base=4
height=2, area=1/2 times 2 times 4=4
square triangle
flip 90 degrees clockwise so we have base=2
height=6
area=1/2 times 2 times 6=6
add
4+6=10
total area=10m^2
