36 inch wire is cut to 2 pieces every piece is of 18 inchthenone shape is square 18/4 is one side of square which is 4.5 inchthen area of square= (4.5)^2 = 20.25
now for the other half shape is rectanglewhere length L is twice the width w so
Area of rectangle = area of square according to our condition
Area of rectangle= W*L
Area of rectangle= W*2W
this is the width of rectangle that will minimize the area
for nearest tenth W= 3 inches
