A 5x7 photo fits in a frame with a 2 1/4 inch boarder. What is the perimeter of the entire shape

148/4

5 + 2 1/4 = 7.25

7 + 2 1/4 = 9.25

P = 2L + 2W

P = 18.5 + 14.5

P = ?

Since the border is on both sides,

5 + 2(2 1/4) = 9.5
7 + 2(2 1/4) = 11.5

2(9.5+11.5) = 42

Ohhh! I sure blew this one.

Thanks, Steve.

To find the perimeter of the entire shape, we need to add up the lengths of all the sides.

First, let's calculate the dimensions of the photo. We know that the photo itself is 5x7 inches.

Next, let's calculate the dimensions of the entire shape, including the border. The border has a width of 2 1/4 inches on all four sides. So we can add 2 times the width of the border to the width of the photo, and 2 times the height of the border to the height of the photo.

Width of the entire shape = Width of the photo + 2 * Width of the border
= 5 + 2 * 2.25
= 5 + 4.5
= 9.5 inches

Height of the entire shape = Height of the photo + 2 * Height of the border
= 7 + 2 * 2.25
= 7 + 4.5
= 11.5 inches

Now that we have the dimensions of the entire shape (which includes the photo and the border), we can calculate the perimeter by adding up the four sides.

Perimeter of the entire shape = 2 * (Width of the entire shape + Height of the entire shape)
= 2 * (9.5 + 11.5)
= 2 * 21
= 42 inches

Therefore, the perimeter of the entire shape is 42 inches.
