To find the length when the area is known, you can use the formula for the area of the shape in question. For example, for a rectangle, the area ( A ) is calculated as ( A = \text{length} \times \text{width} ). Rearranging this formula, the length can be found by dividing the area by the width: ( \text{length} = \frac{A}{\text{width}} ). For other shapes, similar rearrangements of their area formulas can be applied.

How do you find the length of rectangle or square if the area and width are known?
For a rectangle or square, Area = Length * Width So Length = Area / Width.
How do you find volume of a cuboid given the area and length?
To find the volume of a cuboid, you need its length, width, and height. If you have the area of the base (length × width) and the length, you can rearrange the area formula to find the width: width = area/length. Once you have the width, you can multiply the area by the height (if known) or find the height similarly to calculate the volume using the formula: Volume = length × width × height.
What is the length if the area of a square is 81 ft2?
To find the length of a side of a square when the area is known, you can use the formula: Area = side length². Given that the area is 81 ft², you can take the square root of 81 to find the side length. Thus, the side length is 9 feet.
Is the area times or add in maths?
From the known length of the sides, length and width, to find the area you multiply(times) the length X width = Area. If you have a given area and wish to find the total area of an adjacent (next to) area, you add the areas. Area(1) + area(2) = Area (Total(.
How do you find the perimeter of a rectangle if you have the length and the area?
Area = Length*Width so Width = Area/Length. Therefore the Width can be calculated. Then, perimeter = 2*(Length + Width) and everything on the right hand side of the equation is known so the perimeter can be calculated.
How do you find the length of rectangle or square if the area and width are known?
For a rectangle or square, Area = Length * Width So Length = Area / Width.
Can you find the perimeter if you know area of a rectangle?
You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.
What is the length if the area of a square is 81 ft2?
To find the length of a side of a square when the area is known, you can use the formula: Area = side length². Given that the area is 81 ft², you can take the square root of 81 to find the side length. Thus, the side length is 9 feet.
How do uou find the length of a rectangle?

How do you find the length?
To find the length of a triangle or what ever shape your trying to find all you have to do is multiply width times the area. * * * * * Or, if you want the correct answer, you could try to divide the area by the width. That assumes the shape is a rectangle and that the area and width are known!
How do you find the perimeter of a rectangle if you have the length and the area?
Area = Length*Width so Width = Area/Length. Therefore the Width can be calculated. Then, perimeter = 2*(Length + Width) and everything on the right hand side of the equation is known so the perimeter can be calculated.
How do you find the width of a rectangle when you know its area and length?
You divide area by length or area/length.
How do you find the length if you already have the width and the area?
If Length * Width = Area, then Area ÷ width = Length
What is the area of a rectangle is the length is 16 and the primeter is 56?
The area of rectangle is : 896.0
How do you find a square length when you only have the area?
The area of a square is the "length x width" but as these are equal we can put that the area = L2.....where L is the side length of the square. If the value of the area is known then the square root of this figure provides the side length. Example : Area = 36 sq cm, Length L = √36 = 6 cm.
How do you find the length and width of a square if know the square feet?
The length and width of a square by definition are of equal length. The area (A) of a square = d2, where d is the length of one side. If the area is known, then the length of the side of a square, d = √A (square root of A).
