Do Pythagorean theorem. If you don't know what that is...
Do A squared plus B squared Equals C squared and you will get your answer for the shape. Then calculate the area
Answer:
4 units wide
Step-by-step explanation:
Let the width of the table be 'w'
Given:
Perimeter of the table is, ![P=72](https://tex.z-dn.net/?f=P%3D72)
The perimeter of the rectangular table is given as the sum of all the sides of the rectangle. The sides include two lengths and two widths.
Length of the table is 8 times longer than its width. Therefore,
![Length,L=8w](https://tex.z-dn.net/?f=Length%2CL%3D8w)
Now, perimeter is given as:
![P=2L +2w\\P=2(8w)+2w\\P=16w+2w\\P=18w\\w=\frac{P}{18}](https://tex.z-dn.net/?f=P%3D2L%20%2B2w%5C%5CP%3D2%288w%29%2B2w%5C%5CP%3D16w%2B2w%5C%5CP%3D18w%5C%5Cw%3D%5Cfrac%7BP%7D%7B18%7D)
Now, plug in 72 for 'P' and solve for 'w'. This gives,
![w=\frac{P}{18}\\\\w=\frac{72}{18}\\\\w=4](https://tex.z-dn.net/?f=w%3D%5Cfrac%7BP%7D%7B18%7D%5C%5C%5C%5Cw%3D%5Cfrac%7B72%7D%7B18%7D%5C%5C%5C%5Cw%3D4)
So, the table is 4 units wide.
The answer is 3/-2 hope that helps!
