90-33=57
57-1=56
56/2=28

Not sure about the statement
movement down 5 units
move right 2 units
Add 1
0.7+1=1.7
1.7+1= 2.7
etc., etc.
To find the area, move each semicircle to fill up the square, you'll see there are three squares, each with an area of 4*4=16, so the total area is 3*16=48
Now the perimeter:
the perimeter of a circle is π times the diameter.
perimeter of each semicircle: (1/2)π*4=2π
there are altogether 6 arches and two straight sides, so the total is
2π*6+4*2=12π+8
the area is 48 square units, the perimeter is 12π+8 units.
