A rectangular prism or a cuboid.
If it was a square, the answer would be 81 square cm. The area will be the product of two numbers whose sum is half the perimeter.

Depends where you make the cut Across the planes it is a CUBOID Across the corners it is PYRAMID .
They are both polygon. If you cut a rectangle diagonally, you will have two triangles. And if you want to figure out the area of a right triangle, you can treat it as a rectangle and then cut your calculation in half to get the correct answer.

yes, because if you cut the rectangle in half it would make 2 squares

If the side lengths of a rectangle are halved, the perimeter of the rectangle would also be halved. This is because the perimeter of a rectangle is calculated by adding the lengths of all four sides. If each side length is halved, then the total length around the rectangle would also be halved.
The perimeter of a rectangle is just the sum of the lengths of its sides, so taking half of each of the sides would make the total half of its original value also.
If you speak of half of 100 in number would be 50. If you talk about the figure, half of this would be zero.
No. There is no way you can cut one rectangle in half and only get one square. The other half would also have to be a square and this will only happen if the proportions are 1:2 and you cut the long sides.There are infinitely many ways to cut a rectangle in half none of which result in new rectangles. Only if the rectangle has proportions 1:2 can cutting it in half make a square, in fact the result could be two squares, not one.
