thw width of a rectagular poster is 16in.its length is twice its width.find its perimeter

16 + 32 + 16 + 32 = ??

96 To find the perimeter of a rectangular poster, we need to know the formula for perimeter. The formula for the perimeter of a rectangle is:

Perimeter = 2 * (Length + Width)

In this case, the given information states that the width of the rectangular poster is 16 inches. The length is given as twice the width.

So, Length = 2 * Width = 2 * 16 = 32 inches.

Now we can substitute the values into the formula:

Perimeter = 2 * (Length + Width)
= 2 * (32 + 16)
= 2 * 48
= 96 inches

Therefore, the perimeter of the rectangular poster is 96 inches.
