How do you calculate the length and breadth of a rectangle given the area and the perimeter?
Perimeter = (2 lengths) + (2 widths)
1/2 of the perimeter = (length) + (width)
Area = (length) x (width)
So if you're given the area and the perimeter:
-- Look for factor-pairs that multiply to give the area.
-- The right pair of factors is the pair that add to give 1/2 of the perimeter.
Example:
Area = 24
Perimeter = 22
Factor pairs that make 24:
1 x 24
2 x 12
3 x 8
4 x 6
Which pair is it ?
Perimeter = 22
1/2 the perimeter = 11.
Look at the sums:
1 + 24 = 25
2 + 12 = 14
3 + 8 = 11 <===
4 + 6 = 10
The rectangle is 3 by 8 .

How do you find breadth using perimeter and length?
If the shape is a rectangle (or square), then Perimeter = 2*(Length + Breadth) So Breadth = Perimeter/2 - Length

What is the perimeter of a rectangle whose length is 18 cm and breadth is 10 cm?
56 cm Perimeter of a rectangle is given by 2(length + breadth). So, perimeter of given rectangle = 2(18 + 10) = 56
How do you find area and length of a rectangle if perimeter and breadth is given?
Well, isn't that just a happy little problem to solve! To find the area of a rectangle, you multiply the length by the breadth. And to find the length, you can use the formula: length = (perimeter - 2 * breadth) / 2. Just remember, there are no mistakes, only happy accidents in math!
Area and perimeter of a rectangle?
Area is length times width, perimeter is twice the sum of length and breadth.
The breadth of a rectangle is ten less than four times its length. Let x be the length of the rectangle What is the perimeter of the rectangle in terms of x?
breadth = 4x - 10 ie length + breadth = 5x - 10. Perimeter is double this figure ie 10x - 20 or 10(x - 2)
Can you calculate a perimeter of a rectangle but not the length of its sides?
no No. You need to know the length of a rectangle's sides in order to calculate the perimeter.
How does the perimeter of a rectangular change if one of its sides is doubled?
Perimeter of a rectangle = 2(length + breadth) if one of it's side is doubled then, the resultant perimeter will be 2(2length + breadth) or 2(length + 2 breadth) as the case may be.
If a rectangle has perimeter of 1.57 kilomteres its length is 168 meters what is breadth?
Perimeter = 2*(Length + Breadth) So, 1570 = 2*(168 + Breadth) 785 = 168 + Breadth Breadth = 617 metres Which is rather an unusual result because normally the length is greater than the breadth.
