Answer:
Width = 17
Length = 92
Explanation:
Perimeter of rectangle = 2 (length + width)
let us take width be x
length = 7 + 5x
width = x
so let us put these value
2 (length + width) = 218
2 (7 + 5x + x ) = 218
2 (7 + 6x ) = 218
14 + 12x = 218
12x = 218 -14
12x = 204
x = 204/12
x = 17
Width = x
= 17
Length = 7 + 5x
= 7 + 5(17)
= 7 + 85
= 92
