To find the perimeter of the rectangular window frame, we can substitute the given values for the length and width into the expression for the perimeter:
Perimeter = 2(L + W)
L = 21 inches
W = 5 inches
Plugging in these values, we have:
Perimeter = 2(21 + 5)
= 2(26)
= 52 inches
Therefore, the perimeter of the rectangular window frame is 52 inches.
The perimeter of a rectangle is given by the expression below where L is the length of the rectangle and W is the width
2(L +W)
