Answer:
2(x + 34) = 188, 60 inches.
Step-by-step explanation:
The width of a window is 34 inches
and it's perimeter is 188 inches.
Perimeter = 2(length + width)
Let the length of the window be x
Perimeter = 2(x + 34) = 188
2x + 68 = 188
2x = 188 - 68
2x = 120
x = 60
The length of the window is 60 inches.
154
34+x=188
subtract 34 to both sides
x=188-34
x=154
...
45
180-45=135
135/3=45
Check the picture below.
x=15/4 or x=3.75
4/5*x=3
4/5=0.8
0.8*3.75=3
