Perimeter, since it measures the distance around a shape. Area measures the interior. Or, more specifically, height by width, for example, 8x10 or 11x14 (inches). The perimeter for an 8x10 would be 2 times 8 plus 2 times 10, or 36 inches, but that would be insufficient to differentate an 8x10 frame from, say, a 6x12 frame (admittedly a rare size, but still possible.) So, while the common specification of a frame by height and width could be reduced to either perimeter or area, it is never done that way, precisely because important information is lost, the actual usable size of the frame.

In what jobs do you use perimeter or area?
I know an architect does and a pool desighner.
How do you determine perimeter if given the area?
To find area given perimeter, rename perimeter to circumference and solve with these formulas: Circumference = 2πr (or 2 * π * r) Area = πr^2 (or π * r * r) With these the area can be found from circumference(or perimeter) as follows: A = π(C / 2π)^2 Now, to find the perimeter given the area; We use A = πr^2 and rearrange then solve: r = √(A / π) So, the circumference would be 2πr = 2π√(A / π)
Is it possible to make a shape with 28 perimeter and 18 area?
Yes. Use excel with 18 boxes. Offsetting the boxes will get you the right answer.
What is the formula of the area and perimeter?
Example: To find the perimeter of a rectangular box, with length as 6cm and Breadth as 4 cm, we need to use the formula, Perimeter of a Rectangle = 2 (L+B) = 2 ( 6 cm + 4 cm) = 2 × 10 cm = 20cm.
Surface area of a pyramid?
(1/2 B)h another way is Lateral area + base area. Lateral area is 1/2 perimeter*slant height. You use this if you dont know the height but know the slant. or if you just like to do it this way
