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)

What formula expresses the perimeter of a rectangle in terms of its length?
The formula for the perimeter of a rectangle is: p = 2(l + w) In other words, just add all four sides. You can't calculate the perimeter of the rectangle if you know only the length.
A certain rectangle has a width that is half the difference of the length and 6 cm If the Perimeter of the rectangle is 87 cm what is the length and width of the rectangle?
Algebra works great here. Let's use three variables: P for perimeter, L for length and W for width. Then we can rewrite the above in terms of math:W = (1/2)(L - 6)
The length of a rectangle is 2 feet more than the width the perimeter of the rectangle is 20 feet find the length?
let p represent perimeter let w rep. width let l rep. length p = 2l + 2w --> basic perimeter formula l = w + 2 --> two feet more than width 20 = 2(w + 2) + 2w --> sub w + 2 in for l and 20 in for p (given in question) 20 = 2w + 4 + 2w 20 = 4w + 4 --> group like terms 16 = 4w 4 = w if your looking for the width it's therefore 4 feet. and for the length: l = w + 2 l = 4 + 2 l = 6 therefpre the length is 6 feet.
If the perimeter of a rectangle is 64 cm and the length is three times its width what is the area?
Let x = width of the box. We know that the length = 3x, and that the perimeter is 2*length + 2*width, thus we have the equation 2*(3x) + 2*x = 64 => 6x+2x = 64 Combining like terms: => 8x = 64 Solving for x by dividing both sides by 8: x=8 Thus we know that the width is 8, and length = 3*x =3*8 = 24 Area = width*length = 8*24 = 192
What is a golden rectangle?
A golden rectangle is a rectangle where the ratio of the length of the short side to the length of the long side is proportional to the ratio of the length of the long side to the length of the short side plus the length of the long side. It is said to have the "most pleasing" shape or proportion of any rectangle. The math is like this, with the short side = s and the long side = l : s/l = l/s+l Links can be found below to check facts and learn more. In ratio terms, the Golden Rectangle has a width/height ratio of 1.618/1.

How does the length and width of a rectangle relate to the perimeter?
If you add the length and width together, it will always be half of the perimeter. In terms of an equation, it would look like so: Perimeter = (2 x Length) + (2 x Width)
How do you calculate the volume of rectangle hollow piece?
Measure the length and breadth of one face of the rectangle. Measure the thickness of the rectangle hollow piece. Multiply the length, breadth and thickness and this will give you the volume of the rectangular hollow piece in terms of cubic units. That is, if you measured the length, breadth and height in centimeters, the volume will be in cubic centimeters. Example: If the length of the piece is 10 cm, the breadth of the piece is 6 cm, and the thickness of the piece is 5 cm, the volume of the rectangular hollow piece is given by: 10 cm X 6 cm X 5 cm = 300 cubic cm or cm3
Rectangle whose perimeter is larger than area?
Perimeter is a unit of length. Area is a unit of area. The two units are not directly convertible.However, the area of a rectangle is length times width, and the perimeter is two times length plus two times width. Given constant perimeter, a square has maximum area, while a very thin rectangle has nearly zero area. (In calculus terms, the limit of the area as length or width goes to zero is zero.)Depending on how you want to name your units, you can always find a rectangle whose perimeter is "larger" than area, but this is a numerical trick that is not valid in any school of thought of mathematics that I know.
A rectangle has a perimeter of 20 ft Find a function that models its area A in terms of the length x of one of its sides?
Suppose the other side of the rectangle is y, then perimeter = 2(length + breadth) so 20 = 2*(x+y) so that x+y = 10 or y = 10-x Then, A = x*y = x*(10-x) or 10x - x2 Note that x>0, y>0 require that 0<x<10. The function is not defined outside these limits for x.
What is the perimeter of a rectangle which has a diagonal of 8.50 cm and an area of 3000 square mm showing work with answer?
Here is what you are supposed to do: * Convert to consistent units. For example, convert the cm to mm. * Write an equation for the diagonal (in terms of length and width). Replace the known diagonal. * Write an equation for the area, in terms of length and width. * Solve the two equations simultaneously. * Calculate the perimeter.
What is the length and width of a rectangle that has a perimeter of 20 inches and an area of 24.4524 square inches showing work with final answers?
What do we know about the perimeter of a rectangle? perimeter = 2 × (length + width) → 2 × (length + width) = 20 in → length + width = 10 in → length = 10 in - width What do we know about the area of a rectangle: area = length × width → length × width = 24.4524 in² But from the perimeter we know the length in terms of the width and can substitute it in: → (10 in - width) × width = 24.4524 in² → 10 in × width - width² = 24.4524 in² → width² - 10 in × width + 24.4524 in² = 0 This is a quadratic which can be solved by using the formula: ax² + bx + c → x = (-b ±√(b² - 4ac)) / (2a) → width = (-10 ±√(10² - 4 × 1 × 24.4524)) / (2 × 1) in → width = -5 ± ½√(100 - 97.8096) in → width = -5 ±½√2.1904 in → width = -5 ± 0.74 in → width = 4.26 in or 5.74 in → length = 10 in - 4.26 in = 5.74 in or 10 in - 5.74 in = 4.26 in (respectively) By convention the width is the shorter length (though it doesn't have to be) making the width 4.26 in and the length 5.74 in. Thus the rectangle is 5.74 in by 4.26 in
What is length and breadth?
Length and Breath are terms used in golf. Length is the longevity of your swing, back to front. Breath is your breathing pattern during a swing, which should be kept constant.
How do you turn square feet into a perimeter?
A perimeter is a length. It cannot be expressed in terms of area.
A certain rectangle has a width that is half the difference of the length and 6 cm If the Perimeter of the rectangle is 87 cm what is the length and width of the rectangle?
Algebra works great here. Let's use three variables: P for perimeter, L for length and W for width. Then we can rewrite the above in terms of math:W = (1/2)(L - 6)
The length of a rectangle is 8 in more than its widthThe permiter of the rectangle is 24 inWhat sre the width and length of the rectangle?
First, let's call the length of the rectangle L, and the width W.We know that the length is 8 more than the width, i.eL = W+8Now we also know that the perimeter of a rectangle is P=2L+2W, where the P in this case is would be 24.Which gives us 2 equations;L = W+8 [1]24=2L+2W [2]Using simultaneous equations, lets find the perimeter in terms of W, by substituting in the value of L in equation [1]24 = 2(W+8)+2WExpand:24 = 2W+16+2WSimplify:4W + 16 = 24Subtract 16 from both sides:4W = 8W = 2Now substitute W=2 into [1]:L = 2+8L = 10Therefore:The length and width of the rectangle are 10 units and 2 units respectively.
