The length is greater then width with degree one so f(x) = x + 7 and g(x) = x + 3 represents length and width respectively so option (A) will be correct.
A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Perimeter of rectangle = 2( length + width).
A rectangle has two dimensions of size one is greater called length and another is small known as width.
The length and width both are on units of length only such that meter, cm.
In the given option
x + 7 > x + 3 so f(x) will be length and g(x) will be width.
In the option (B) x - 7 < x - 3 so it will not.
Option (C) x² + 7 can not be a unit of length.
Option (D) x - 7 < x - 3 so it will not.
Hence "The length is greater then width with degree one so f(x) = x + 7 and g(x) = x + 3 represents length and width respectively".
