for area you times the two numbers and for perimeter you add the numbers
A simple example would be a square that is ten inches by ten inches. To find the area multiply the length by the width, 10 x 10 = 100in2 (or 100 square inches). To find the perimeter of the square, 10 + 10 + 10 + 10 = 40 inches (or 10 x 4 = 40 inches).

What are formulas for area and perimeter?
Perimeter is the distance around the figure. Add all sides. Area depends on the figure. Triangle --- 1/2 bh Rectangle --- lw. Others --- divide into triangles and find the area of each triangle then add all together.
To find the surface area of the three dimensional figure you must find the perimeter of a face and then multiply by the height?
NO. This is the way to get the volume of a prism, not the surface area of any three-dimensional figure. To find the surface area of a three-dimensional figure, you must find the area of each of its faces and then add the side-areas together.
How to find the perimeter and area of a rectangle?
To find the perimeter you add and to find the area we multiply.
How do you find the perimeter of a heptagon shape?
You find perimeter by adding all the sides of a figure.
To find the surface area of a three-dimensional figure you must find the perimeter of a face and then multiply it by the height.?
That is not true: for a pyramid, for example.
How do you find the distance around a figure?
To find the distance around a figure, you calculate the perimeter. The perimeter is the total distance around the outside of a shape or figure. To find the perimeter of a rectangle or square, you add up all the sides. For a circle, you can find the perimeter by multiplying the diameter by Ο (pi).
How do you find area when given perimeter and width?
If you are given the width and the perimeter, then figure out what the length is then calculate the area... hope this helps :)

How do you find the perimeter and area of a irregular figure?
Divide the irregular figure into manageable pieces and work out their individual areas, sum the areas to that of the original figure. Measure the perimeter.
How can you find the ratios of their pereimeters and area?
1). Calculate the perimeter of the figure. 2). Calculate the area of the figure. 3). Divide one by the other.
How do you perimeter?
To find the perimeter of a figure, add all the lengths of the edges of the figure. The sum of the sides is the perimeter.
Can you find the perimeter with only the area?
No, you also need some details about the specific figure you are working with.
When finding the perimeter of a figure on a grid why do you not count the spaces inside the grid?
That's because "perimeter" means the distance around something - not the spaces inside. If you count squares inside a figure, you are finding the AREA, not the PERIMETER.
How do you find surface area of a triangular prisim?
2*area of triangular faces + perimeter of triangle*length of prism (not prisim).
What are formulas for area and perimeter?
Perimeter is the distance around the figure. Add all sides. Area depends on the figure. Triangle --- 1/2 bh Rectangle --- lw. Others --- divide into triangles and find the area of each triangle then add all together.
How do you find the lateral area of a rectangular prism?
L=PH L=PH Lateral Area= (Perimeter of the base)(the height of the figure)
To find the surface area of the three dimensional figure you must find the perimeter of a face and then multiply by the height?
NO. This is the way to get the volume of a prism, not the surface area of any three-dimensional figure. To find the surface area of a three-dimensional figure, you must find the area of each of its faces and then add the side-areas together.
