Based on the calculations, we have the following:
- The area of the sheet of paper is 96 square inches.
- The combined area of the triangle cutouts is equal to 36 square inches.
- The area of the parallelogram is equal to 60 square inches.
- The altitude of the parallelogram is equal to 6.51 square inches.
<u>Given the following data:</u>
- Dimension of paper = 12-inch by 8-inch.
<h3>How to calculate the paper's area.</h3>
Mathematically, the area of the paper is given by this formula:
![Area = length \times breadth\\\\Area = 12 \times 8](https://tex.z-dn.net/?f=Area%20%3D%20length%20%5Ctimes%20breadth%5C%5C%5C%5CArea%20%3D%2012%20%5Ctimes%208)
Area = 96 square inches.
<u>For the four (4) right triangles:</u>
- Dimension 1 = 2 inches by 9 inches.
- Dimension 2 = 3 inches by 6 inches.
Therefore, the combined area of the triangle cutouts is given by:
![A_2= (2 \times \frac{1}{2} \times 2 \times 9) + 2 \times \frac{1}{2} \times 3 \times 6\\\\A_2=18+18\\\\A_2=36\;in^2](https://tex.z-dn.net/?f=A_2%3D%20%282%20%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%202%20%5Ctimes%209%29%20%2B%202%20%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%203%20%5Ctimes%206%5C%5C%5C%5CA_2%3D18%2B18%5C%5C%5C%5CA_2%3D36%5C%3Bin%5E2)
<h3>The area of the parallelogram.</h3>
This would be determined by subtracting the area of the four (4) right triangles from the areas of the paper as follows:
![P = A_p -A_2\\\\P=96-36](https://tex.z-dn.net/?f=P%20%3D%20A_p%20-A_2%5C%5C%5C%5CP%3D96-36)
P = 60 square inches.
<h3>The altitude of the
parallelogram.</h3>
![P = base \times altitude\\\\Altitude =\frac{P}{base} \\\\Altitude =\frac{60}{9.22}](https://tex.z-dn.net/?f=P%20%3D%20base%20%5Ctimes%20altitude%5C%5C%5C%5CAltitude%20%3D%5Cfrac%7BP%7D%7Bbase%7D%20%5C%5C%5C%5CAltitude%20%3D%5Cfrac%7B60%7D%7B9.22%7D)
Altitude = 6.51 square inches.
