ABCDE is a regular pentagon. Quantity A x Quantity B 36
A thin metal plate in the shape of a parallelogram has an area of 80 square inches and is cut into two pieces using two cuts. Each cut is parallel to a side of the plate, as shown, and the ratio of the length of each cut to the length of the side of the plate to which the cut is parallel is 3 to 4. What is the area, in square inches, of the piece of the plate represented by the shaded region?
In square MNOP shown, the two shaded square regions have areas in the ratio 9 to 1. If square region MNOP has area 144, what is the area of each of the two unshaded rectangular regions?

The figure above shows a ceramic tile in the shape of an equilateral triangle with sides of length 12 inches. Parts of the tile are gray, as represented by the shaded regions, and the rest of the tile is white. The equilateral triangle in the middle of the tile has sides of length 9 inches and consists of nine congruent equilateral triangles. What fraction of the area of the tile is gray?
Each side of a triangle has a length of 1 Quantity A: The area of the triangle Quantity B: $$\sqrt{2}$$
The figure consists of 14 identical equilateral triangular regions. If the area of the figure is $$56\sqrt{3}$$, what is the total length of all the sides shown in the figure?
The lower sides of the two equilateral triangles are parallel. If the side of the bigger equilateral triangle is 36, and the perimeters of the smaller equilateral triangle and the trapezoid beneath are the same, what is the side of the smaller equilateral triangle?
