The prism shown below will be sliced by a plane perpendicular to the base along the dotted line AB. Points A and B are mid points of the equal edges.

A triangular prism of height 8 cm is shown. The base of the prism is an isosceles right triangle with equal sides of 10 cm. A dotted line joining points A and B is shown on the top face of the prism. A rectangular cross section sliced by a plane perpendicular to the base along the dotted line AB is shown.

What will be the approximate area of the shaded cross section?
57 cm2
112 cm2
80 cm2
70 cm2
