what is the relationship between scale factor and perimeter?

The perimeter of a scaled object will be equal to the scale factor. If the scale factor is three, then the perimeter of the new object will be three times the original perimeter. The area of a scaled object will be equal to the scale factor squared.

Remember the formulas for both area and perimeter of a square. The area of a square is a = s 2, or side times side, while the perimeter is p = 4s, or 4 times s.

Area and Perimeter Relations If two triangles are congruent, then they will have the same area and perimeter. If two triangles are similar in the ratio R R R, then the ratio of their perimeter would be R R R and the ratio of their area would be R 2 R^2 R2.

For perimeter just add up the length of all the outer walls. For area multiply the width of the house by the depth if it's a simple rectangle. Otherwise split up the plan of the house into separate rooms or rectangles, measure the area of each room or rectangle by length x width and add them all up.

The perimeter of a parallelogram is the distance around the outside of the parallelogram. A parallelogram has four sides with opposite sides being congruent. The formula for finding the perimeter is Side A + Side B + Side A + Side B. This could also be stated as 2*Side A + 2*Side B or 2*(Side A + Side B).

The perimeter is the sum of all sides of a figure to get one length. So, to find the perimeter, the formula is base + height + base + height. If the base is 10 inches and the height is 5 inches, you would have: Perimeter: 10 + 5 + 10 + 5 = 30 inches.

4 Answers. The relationship is a simple inverse, i.e. If you keep the same object and the same focal length you get: size = 1/ distance (the =-sign should be proportional-sign).

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The perimeter, P, is: P=x+x+y+y.

Parameter is a limit that affects how something can be done, and perimeter is the outline of a physical area. ... Some linguistic snobs don't like parameter's meaning of a boundary or limit when perimeter would do.

Multiply the length of one side of a regular polygon by the number of sides to find its perimeter. Regular polygons have identically sized sides. For example, if the shape is a regular pentagon, which has 5 sides, with a side length of 4 inches, then multiplying 4 inches by 5 results in a perimeter of 20 inches.

Size is the physical dimensions of an object. Scale is the relative size of different objects in relation to each other or a common standard. ... In design when we talk about scale we're usually talking about size, however scale is simply a relative comparison of some measurable quality.
