Answer:

Rectangular Prisms: Most Skyscrapers, a cardboard box, and a book

Triangular Prism: Camping Tent and Slice of Cake.

Step-by-step explanation:

Rectangular Prisms: Most skyscrapers are rectangular prisms because they have 4 very long sides and 2 smaller sides. A cardboard box can be a rectangular prism for the same reasons. And a book, even though it doesn't look like a normal one, it still is a rectangular prism.

Triangular Prism: A Camping tent has 2 short triangular sides and 3 rectangular sides. A slice of cake has 2 tall triangles and 3 other rectangular sides. These fall under the category of a triangular prism.

Answer:

A. $\frac{(a-b)^{2} +b^{2} }{a^{2}}$

Step-by-step explanation:

So to get the area of a square, we need to find the length of one side.

We know the length of the larger square is a, so the area of the larger cube is $a^{2}$

We can find the length of a side of the smaller square by using pythagoreans theorem to find the hypotenuse of the triangle formed in the bottom left corner. The length of one side along the x axis is a - b, and the length of the other side, along the y-axis, is b.

We can plug it into pythagoreans theorem to get

$(a-b)^{2} +b^{2} = C^{2}$ (C represents the length of one side of the smaller square, and the hypotenuse of the triangle)
