The formulas used to find the perimeter of a rectangle or square are only used for two-dimensional objects, so they cannot be used to find the perimeter of a three-dimensional box. The term perimeter refers to the distance around a polygon, which is a two-dimensional shape with at least three sides.Continue Reading
The formula for calculating the perimeter of a rectangle is 2L + 2W, where L is the length of the rectangle and W is the width of the rectangle. If a rectangle has a length of 2 feet and a width of 4 feet, its perimeter equals 12 feet, or 2(4) + 2(2).
The formula for calculating the perimeter of a square is 4a, where a is the length of one of the sides of the square. If each side of the square has a length of 3 feet, the perimeter of the square is 12 feet, or 4(3).Learn more about Science
The perimeter of a rectangle is the sum of the length of all four sides. Alternate formulas for finding the perimeter are 2(length + width) and 2 x length + 2 x width.Full Answer >
Common formulas in the study of geometry include calculating the perimeter and area of shapes. For example, the perimeter or outside of a rectangle is the length plus the width of the rectangle times two.Full Answer >
To cut a photo into a heart shape, fold the photo in half; it can be folded like a rectangle of a square depending on the shape of the photograph. Draw an outline of half a heart on the photo, starting and ending the outline at the crease of the folded photo. Cut along the outline, separate the heart shape cut-out from the rest of the photo and unfold the photograph.Full Answer >
The area of a square or rectangle is equal to its width times its height. The sides of a perfect square are all equal, so the formula for a square is also area = x (squared), where "x" is the length of one side.Full Answer >
