Q&A for How to Find Area and Perimeter

The perimeter of a shape is the total distance of the length of the lines that create the border and the area is the total amount of surface the shape takes up in a two-dimension plane. An easy way to remember it is that the perimeter is the length of the fencing you would need to surround your yard, while the area is how much grass you'd need to completely cover it.

No. You could compute area from perimeter and shape, but not from perimeter alone.

Assuming the room is square or rectangular, you would measure the length and width. Multiply the length by the width to get the area, and add twice the length to twice the width to get the perimeter.

Twice the length plus twice the width.

If it's a regular hexagon, the formula is A = (3s²√3) / 2, where s is the length of a side. If it's not a regular hexagon, you would have to break down the floor plan into sections (squares, rectangles, and/or triangles), calculate the areas of each section, and add them together.

The perimeter of a triangle is all the sides combined, so if all the sides equal 11 meters, then it would be 11+11+11 since a triangle has three sides. The final answer would be 33.

If you mean a sector of a circle, you have to know the circumference of the circle and the central angle of the sector. Divide the central angle by 360°, express that as a fraction, and multiply that number by the circumference of the circle. That's the length of the sector's arc. Add to that twice the radius of the circle, and that's the perimeter of the sector.

Divide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area. In this example, 14 ÷ 4 = 3.5. (3.5)² = 12.25 square feet.

It is the sum of the lengths of the sides.

One side of a square is the square root of its area, and the perimeter is four times the side.

Perimeter. The word itself actually means "around the edge".

You would also have to know all of the angles along the perimeter. You would then use geometry and/or trigonometry to find the area of the property (in square units) and then use the appropriate conversion factor to find the acreage.

Each step has a length and a width (or dimensions of some sort). Use the formulas above to calculate the area of each step, then add them together.

By definition, an "area" is closed. If it's not actually closed, you will have to "close" it artificially before you can measure it in order to calculate the area.

See Find the Perimeter of a Rhombus .

No. A perimeter is the distance all the way around a closed shape.

To find either, you would have to know both the length and the width of the rectangle. The perimeter is twice the length plus twice the width. The area is length multiplied by width.

2(6)+2(10)=32 meters. Multiply the width and length by 2 so that you can get the perimeter.

Yes. The area would be 1 square unit (or 1 unit squared).

Multiply base by height to calculate the area of a parallelogram.

Multiply pi by the square of the radius. Then multiply that by 3/4.

Take half the perimeter. From that subtract the width. That's the height (or length).

An irregular shape must be subdivided into smaller shapes of known or calculable dimensions. Each area must be calculated and added together.

If you're referring to a triangle, the area is half the product of the base and height. To find the perimeter, however, you would need additional information such as the other side lengths or the size of the angles. For other shapes, the requirements are different in each case.

It depends on which side and which angle are given. You would use known sides, angles and trigonometry to find the unknown side(s) and/or the height so you can calculate the perimeter and area.

There are no formulas applicable to irregular shapes. Each such shape would have to be subdivided into smaller shapes of calculable dimensions and then added together.

Divide by 4 like 4/4=1. So, cutting in quarters is how to find out the answer to the question
