Perimeter = 2(l+w) or 2(length+width)
So far you have the width, which is 19feet. Since you have two sides of the rectangle which are 19 feet, add 19+19=38
Subtract 62-38 to get 24.
You now have the length of both of the sides combined. So you need to divide 24/2 = 12
The length of the rectangle = 12ft.
8 1/4 is given as a positive number so you could write it as +8 1/4
The opposite of positive is negative, so you would have -(+8 1/4)
The answer is A
Step-by-step explanation:
![\frac{7}{30}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B30%7D%20)
![\frac{5}{6} + ( - \frac{3}{5} ) \\ lcm = 30 \\ \frac{25 + ( - 18)}{30} = \frac{7}{30}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B6%7D%20%20%2B%20%28%20-%20%20%5Cfrac%7B3%7D%7B5%7D%20%29%20%5C%5C%20lcm%20%3D%2030%20%20%5C%5C%20%5Cfrac%7B25%20%2B%20%28%20-%2018%29%7D%7B30%7D%20%20%3D%20%20%5Cfrac%7B7%7D%7B30%7D%20)
