Answer:
The missing part is given below.
500=(2xL)+(__2__x_90___)
500=2L+__180_____
_320__=2L
_320____ divided by 2=L
_160____=L
Step-by-step explanation:
Given:
Perimeter of Rectangle = 500 feet
Width = 90 feet
Length = L
Solution:
[tex]\textrm{Perimeter of Rectangle} = 2(Length + Width)\\\\\textrm{On substituting the given values in it we get}\\500 = 2\times L + 2\times 90\\\\500 - 180 =2\times L\\320 =2\times L\\\\\frac{320}{2}=L\ ....................... (\textrm{320 divided by 2}) \\160 = L[/tex]
