How long are the diagonals of a 9 x 12 rectangular picture frame?

According to the "3-4-5" law of right triangles, if the two sides of the triangle are 3 units and 4 units, the hypotenuse must be 5 units. So a diagonal must be 15 inches. The sides are 3 * 3 and 3 * 4, so the diagonal is 3 * 5.

How long is the diagonal of a 12 mm-by-16 mm face of a rectangular prism?

To find the diagonal of a rectangular face, you can use the Pythagorean theorem. For a rectangle with sides of 12 mm and 16 mm, the diagonal ( d ) is calculated as ( d = \sqrt{12^2 + 16^2} = \sqrt{144 + 256} = \sqrt{400} = 20 ) mm. Thus, the diagonal of the 12 mm-by-16 mm face is 20 mm long.


Alyssa has made a picture frame.The frame is 60 cm long and 25 cm wide.To check that the frame has square corners,Alyssa measures a diagonal.How long should the diagonal be?

65cm Use the Pythagorean theorem. A^2+B^2 = C^2. So the square root of 60^2+25^2.


Helen has a rectangular garden that measures 65 meters by 20 meters. How long is the diagonal length of the garden (An example of diagonal length is from the top left corner to the bottom right corner?

To find the diagonal length of Helen's rectangular garden, you can use the Pythagorean theorem. The formula is (d = \sqrt{l^2 + w^2}), where (l) is the length and (w) is the width. Substituting the measurements, (d = \sqrt{65^2 + 20^2} = \sqrt{4225 + 400} = \sqrt{4625}). The diagonal length is approximately 68.06 meters.

How many 8 ft boards needed for a frame 3x4 with a diagonal?

To create a frame measuring 3 feet by 4 feet with a diagonal, you will need to calculate the perimeter and add the diagonal length. The perimeter of the rectangle is 2(3 + 4) = 14 feet. The diagonal can be calculated using the Pythagorean theorem: √(3² + 4²) = 5 feet. Therefore, the total length needed is 14 + 5 = 19 feet. Since each board is 8 feet long, you will need 3 boards (2 for the perimeter and 1 for the diagonal).

is there a good place for picture frames?

Any place is perfect for a picture frame. As long as things aren't busy (cluttered), whenever there is a picture frame it simply invites someone to imagine a story or a meaning behind it all. They express who you are and what experience you have shared with friends and loved ones.
