Output # 1 Meet My Demands
Mr. Lakandula would like to incr8,e0a0s0 e his production of milkfish(bangus) due to high demand in the market. He is thinking of
making a larger fishpond in his sq. m lot near a river. Help Mr. Lakandula by making a sketch plan of the fishpond to
be made. Out of the given situation and sketch plan made, formulate 3 quadratic equations then solve them by factoring.
Your work will be rated using the rubric below.
