Fraction PSLE 2010 P1 Q30

30.  In the diagram below, ACEG and BDFH are squares. AB, CD, EF and GH are of the same length. The ratio of AB: BC is 2:1.




What fraction of the square ACEG is shaded?


3  x  3  =  9

4  x  1/2  x  1  x  2  =  4

9  -  4  =  5

5/9

    As appeared in PSLE 2010 exam:

    In the diagram below, ACEG and BDFH are squares. AB, CD, EF and GH are of the same length. The ratio of AB: BC is 2:1.
    What fraction of the square ACEG is shaded?

    Diagram given:
    Start from point A at the left hand corner. Point A passes point B and end at point C (right hand corner). Point C goes down, passes point D and end at point E (right hand bottom). Point E passes point F and ends at point G (left hand bottom). Point G goes up, passes point H and ends at point A.

    Ratio of length:
    AB: BC -> 2:1
    CD: DE -> 2:1
    EF: FG -> 2:1
    GH: HA -> 2:1

    Join points H,B,D and F to form a shaded area (square BDFH)inside the square ACEG.
