Answer:
Width = 50ft
Length = 160ft
Explanation:
Given parameter:
The perimeter of the flag is 420ft
Unknown:
Length of flag = ?
Width of flag = ?
Solution:
To solve this problem;
Perimeter of the flag is given as:
Perimeter = 2(Length + width)
Length =110 + Width
Now insert the parameters:
420 = 2(110 + Width + Width )
let w = width
420 = 2(110 + 2w)
420 = 220 + 4w
4w = 200
w = 50ft
Length = 110 + 50 = 160ft
