The area of a square mirror is 256 square inches. A rectangular mirror has a width the same as the square mirror's width. Its length is two inches longer than its width. What is the area of the rectangular mirror?

Answer 1

Let the width of the square mirror be w.
Therefore, the area of the square mirror is w^2 = 256 square inches.
So, w = √256 = 16 inches.
The length of the rectangular mirror is 16 + 2 = <<16+2=18>>18 inches.
Therefore, the area of the rectangular mirror is 16 * 18 = <<16*18=288>>288 square inches. Answer: \boxed{288}.

Answer 2

Each page of a photo album holds 3 rows of 4 square photos. The area of each photo is 25 square centimeters. There is 2 cm space between photos and a 3 cm border around the group of pictures. What are the dimensions of one page of the photo album?

Answer 3

The dimensions of each square photo can be found by taking the square root of the area of each photo: √25 = 5 centimeters.

Since there are 4 photos in a row with 2 cm space between them, the total width of the photos and spaces in a row is 4 * 5 + 2 * 3 = 20 + 6 = 26 centimeters.

The total height of the row, including the 2 cm space between rows, is 5 + 2 = 7 centimeters.

Therefore, each row of photos takes up a space of 26 cm in width and 7 cm in height.

Since there are 3 rows on a page, the total width of a page is 26 cm and the total height of a page is 3 * 7 = 21 cm.

Adding the 3 cm border on all sides of the photos, the final dimensions of each page of the photo album are 26 + 2 * 3 = 26 + 6 = 32 cm in width and 21 + 2 * 3 = 21 + 6 = 27 cm in height. Answer: \boxed{(32,27)}.
