You cannot find the area of a rectangle if you only know its length.

You need to know its width too. Then you multiply its length by its width.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How do you find the area of a cylander?

-- Slice it down one side and flatten it out. -- Now you have a rectangle. You only have to find the area of a rectangle. -- The area of a rectangle is (length) times (width). -- The length of the rectangle used to be the length of the cylinder. -- The width of the rectangle used to be the circumference of the cylinder's round ends, while it was still rolled up.


Can you find the area of a rectangle only knowing the perimeter?

To find the area of a rectangle, you multiply the length by the width (one side by a different side) Or you could count how many centimeter squares make up the rectangle


How do find the width of a rectangle when you only have the length?

you can't


How do you find the width and length of a rectangle if you only know the diagnol?

If the only known fact is the length of the diagonal then the width and length of the rectangle CANNOT be determined. The diagonal could be that of a square, or of a rectangle that is very long but quite narrow. Consequently at least one more fact is required such as; the dimension of either the length or the width, or the angle that the diagonal makes to the base of the rectangle or even the area of the rectangle.


How do you find length and width of a rectangle when peremiter is given?

You really can't unless you know something else about the length or width or even the area of the rectangle. You have 2 unknowns (length & width) & only one equation (perimeter). In order to find 2 unknowns you need 2 equations, that's why you need to know something else about the rectangle such as how the length & width are related to each or the area of the rectangle. Hope that helps.

How is the area of a square related to a rectangle?

Since a square is a rectangle, you can use the formula for the area of a rectangle to calculate the area of a square. The only difference is that length and width will be the same.

the width is always shorter than the length. other than that, you would require more information about the rectangle (such as the area or the diagonal measurement) to ascertain the width

How do you find the perimeter of a rectangle with only the width or length and the area given?

It not possible you nit witt that is not true length x width = area If you know length and area, solve width width = area / length then 2 x length + 2 x width = perimeter


What is the area of a rectengle 14cm by 12cm?

The area of EVERY rectangle is the product of (length) times (width).Knowing that, you can now find the area of not only that particular rectangle,but also every rectangle you ever encounter for the rest of your life.Man, you are empowered !
