Let the length be 3x and the width be x:
3x*x = 243
3x2 = 243
Divide both sides by 3:
x2 = 81
Square root both sides:
x = 9
Therefore: length = 27 cm and width = 9 cm

How do you find height when length and breadth are given in rectangle?
A rectangle is a 2-dimensional object. It cannot have length and breadth AND height. If three dimensions are given, then two of them (eg breadth and height) must stand for the same thing.
We are interested in the dimensions of a certain rectangle. This rectangle has length twice the side of the square and width three units less than its sides of this square. If the two areas are equal?
The rectangle is 12 units by 3 units.
The length of a rectangle is equal to three times its width if the perimeter is equal to 40 feet what is the length of the rectangle?
15 feet.
Why area of rectangle is lbh?
I assume lbh in the question means length, base (or width) and height. Those three dimensions multiplied together calculate the volume, not the area, of the figure for cubic dimension. The area is calculated by multiplying the length and the width for squared dimension. In simpler terms; Area of rectangle is lw; Volume is lwh.
He length of a rectangle is three times its width. If the area of the rectangle is 192 m2 find its perimeter.?
64 meters
Show the height width length of a rectangle?
A rectangle is a two dimensional object: height, width and length are three dimensions.
What is caluated by multiplying the length of a rectangle by its width and height?
A rectangle has only two dimensions, for example, length and width. If you multiply that, you get the area. A rectangular box has a length, width, and height. If you multiply all three, you get the volume.
What is meant by rectangular unit vector?
A unit vector has a length (magnitude) equal to 1 (one unit). A rectangular vector is a coordinate vector specified by components that define a rectangle (or rectangular prism in three dimensions, and similar shapes in greater dimensions). The starting point and terminal point of the vector lie at opposite ends of the rectangle (or prism, etc.).

If the perimeter of a rectangle is twenty four inches find the dimensions if its length is three times the height.?
That would be 3 x 9 inches.
What isnthe definition of length?
The measurement or extent of something from end to end; the greater of two or the greatest of three dimensions of a body.
Why is volume in cube units?
Because volume has three dimensions: A line has one dimension: length An area has two dimensions: length and width Volume has three dimensions: length, width and depth.
The length of a rectangle is three times its width If the perimeter of the rectangle is 486in2 what is its area?
the length is equal to 160,083
What is single dimension?
One dimension: Length Two dimensions: Length, Width Three dimensions: Length, Width, Height
The perimeter of a rectangle is 28 inches if the length of the rectangle is three inches more than three times the width find the dimensions?
L + W = 28/2 = 14 L = 3 + 3W, so 3 + 3W + W = 14 ie 4W = 11 so width is 2¾" and length is 11¼"
Name a shape with 4 sides?
square, rectangle etc. In two dimensions: a quadrilateral. In three dimensions: a tetrahedron.
