Answer: The perimeter of a rectangle is given by the formula P = 2L + 2W, where L is the length and W is the width of the rectangle.
We know that the rectangular school banner has a length of 44 inches and a perimeter of 156 inches. And we can use the formula above to find the width of the rectangular school banner:
P = 2L + 2W = 156 inches
P = 2(44) + 2W = 88 + 2W = 156 inches
So the width of the rectangular school banner is W = 156 inches - 88 inches = 68 inches
Now, we know that the cheerleaders make signs similar to the banner. the length of a sign is 11 inches, we can use the same formula to find the perimeter of the sign.
P = 2L + 2W = 2(11) + 2W
So the perimeter of the sign is P = 22 + 2W inches
Since we don't know the width of the sign (W) we can't find the perimeter of the sign.
