niran has 72 centimeter of molding to make a frame for a print. how should he cut the molding to give the largestpossible area for the print using the inside edge of the moldin as the perimeter
The question does not state the shape of the print. The largest area is made by NOT cutting the moulding and bending the moulding into a circle.
Radius will be 72/2xpi =11.46 cm
Area = pi r^2= 3.142 x 11.46cm^2= 412 cm^2
By comparison if the moulding is cut into 4 equal pieces the area is
18cm^2 = 324 cm^2
