Answer by checkley71(8403) (Show Source): You can put this solution on YOUR website!
THE MAXIMUM AREA OF A RECTANGLE IS IN THE FORM OF A SQUARE.
SEING AS THERE IS ALREADY ON SIDE YOU NEED TO FIND THREE ADDITIONAL SIDES OF EQUAL LENGTH.
20 PIECES OF 2.8 METERS=56 METERS
56/3=18 2/3 METERS IS THE LENGTH OF EACH OF THE 3 SIDES.
THUS THE ENCLOSED AREA=56/3*3=56 M^2.
--------------------------------------------------
40 PIECES=40*2.8=112 METERS.
112/3=37 1/3 METERS IS THE LENGTH OF EACH OF THE 3 SIDES.
THUS THE ENCLOSED AREA=112/3*3=112 M^2.
