The surface area is quadrupled.
No. The change of the area is the square of the change of the length and width.If the length and width are 40% more, they got multiplied by 1.4 .So the area got multiplied by (1.4)2 = 1.96 . That's an increase of 96% .
Area = length x width Length = area/width
if length and width are doubled then the volume should mulitiply by 8
well change it into another quadrilateral and then take away the area of the lines you added
