l = Length
W = breadth or width
perimeter = 2 x (L+W) = 2L + 2W
2(length+breadth)=Perimetre Length= (Perimetre/2)-Breadth Area=Length x breadth
56 cm Perimeter of a rectangle is given by 2(length + breadth). So, perimeter of given rectangle = 2(18 + 10) = 56
By halving its perimeter and using the quadratic equation formula.
There is no "the" formula. The answer depends on what you are looking for: perimeter, length of side, diagonal, area, angles; and what information you have.For example, given the length of a side (s) and an angle (A), Area = s^2*sin(A).The question needs to be more precise in terms of what is required.
The answer depends on what information is given to you.
2(length+breadth)=Perimetre Length= (Perimetre/2)-Breadth Area=Length x breadth
56 cm Perimeter of a rectangle is given by 2(length + breadth). So, perimeter of given rectangle = 2(18 + 10) = 56
Let the length be x: 2*x = perimeter-(2*breadth) Then divide both sides by 2 to find the vallue of x
let the length be 'x' and the breadth be 'y' then area = xy and perimeter = 2x+2y Solve the simultaneous linear equations by given area and perimeter. Regards, A Pakistani!
we have the formula to find perimeter of the rectangle i.e. perimeter = 2(l+b) where l = length b = breadth substitute l=96 and perimeter = 334,we get 334 = 2(96+b) 334/2=96+b, 167 = 96 + b b = 167-96 =71. b = breadth of the given rectangle is 71.
Length = (Perimeter - twice width) / 2
There is no formula for a rectangle. There are formula for calculating its area, perimeter or length of diagonals from its sides, or it is possible to calculate the length of one pair of sides given the other sides and the area or perimeter, or the two lots of sides given area and perimeter and so on.
All you need to do is length x breadth = area
The answer depends on what information you are given: (volume, breadth and height), (surface are, breadth and height), (principle diagonal, breadth and height), (mass, density, breadth and height) or some other set.
The formula for measuring the area of a square is s2, where s is the length of one of the sides. The perimeter would be 4s.
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.
Divide the area by the length of the rectangle
