The expression represents the perimeter, in centimeters, of the rectangle C. 2s+24r.
The fringe formula for a rectangle states that, in which P represents perimeter, L represents duration, and W represents width. while you are given the scale of a rectangular form, you can genuinely plug in the values of L and W into the system so as to resolve for the perimeter.
Perimeter = 2 ( length + width)
Where,
Width = (5r+8s)
Length = (7r-7s)
substituting into the formula:-
Perimeter = 2 { (5r+8s)+ (7r−7s) }
Perimeter = 2 { 5r + 7r + 8s - 7s }
Perimeter = 2 { 12r + s}
Expand bracket
Perimeter = 24r + 2s
