The corners of a square are cut off two centimeters from each corner to form an octagon. If the octagon is 10 centimeters wide, what is its area?

Step-by-step explanation:

Area of octagon = area of square - area of 4 triangles that are formed in four corners

Area of square:

Side = Width of the octagon = 10 cm

Area = side * side

       = 10 * 10

      = 100 cm²

Area of triangle:

Base =  2cm

height =  2 cm

Area =

        =

       = 2  cm²

Area of octagon = 100 - 2 =  98  cm²

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
