You ONLY multiply the length and width, which is the two sides that aren't the same. If you can't figure it out, multiply one side by 2 and the other side by two, and add those products together to get the area.
Here is the formula for area and perimeter:
Area: L x W
Perimeter: 2L +2W

Why do you find the area of all the sides then multiply it by two to find surface area?
because you do

Area you multiply 2 sides and perimeter you add all the sides together.
What is the area of a square if one side is two and a half feet?
definition of a square: all sides are congruent (equal) Therefore, all sides are 2.5 feet. To find area, you multiply length by width....so multiply 2.5x2.5
How do you calculate the perimeter and area of a shape?
Perimeter: add all sides area: multiply length times width for rectangles
How do you find the perimeter and area and formula on a rectangle?
for area you multiply length times width and for perimeter you add all of the sides together
Do you multiply all the sides in area?
no add the sides of the area
Do you times all the sides in area?
If you are calculating the area of a rectangle, it is length times width. You are not multiplying all the sides, because there are four sides. You only need to multiply two of them.
Do you multiply all of the sides to find area?
No. But the exact formula depends on the shape that you are talking about.
What are the formulas for area and perimeter?
to find the perimeter you must add all sides. and to find area you have to multiply lenght and width
What is the area of a square with 5cm sides?
20cm daftie!! ^No, 25cm² actually. All you do is multiply 5 by 5.
How fo you find the area of a polygon?
Multiply the sides
How do you get the area of a square?

How do you out the area of a figure?
Multiply two adjacent sides- that will give you the area of one face. Then multiply by six- a cube has 6 faces. That will give you the surface area of the cube.
When you multiply the dimensions of a rectangular prism by 2 why is the new surface area four times larger?
because you are counting all of the sides
How do you find the area of a quadrilateral if only of its four sides are known?
The only way to find the area is to have two sides to multiply them together unless you have the hypotenuse.
