Question

ODEF is a square. In terms of a, find
-point e is (2a, 2a). point f is (0, 2a). point o is (0,0) and point d is (2a, 0)
2. The area of the square
3. The midpoint of FD
4. The midpoint of OE

Answer 1

    2.  Each side is 2a long.  The area is:

             Area = side²
             Area = (2a)²
             Area = 4a²

  

    3.  The midpoint of FD = ((0+2a)/2,(2a+0)/2) = (a,a)

    4.  The midpoint of OE = (0+2a)/2,(0+2a)/2) = (a,a)
