Best Answer

P = 2L + 2W

P = 2(L + W)

P/2 = L + W

If the perimeter is given and you know one of the side measure length (i.e mL), then you can find the measure length of the other sides.

If you know the measure length of L, then the measure length of W is P/2 - L = W,and vice versa.

A rectangle has a length of 12m and a width of 6m what are the perimeter of the rectangle?

The formula for finding a rectangle's perimeter is 2(l+w).Here, length is given as 12 m & width as 6m. So, the correct answer is2(l+w)=2(12+6)=2 x 18=36m.


Formula of a rectangle?

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.


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.


The length of a rectangle is 3 inches more than its width and its perimeter is 22 inches Find the width of the rectangle?

Perimeter = length + width + length + width = 2 x (length + width) Given: perimeter = 22in length = width + 3in Thus 22 = 2 x (width + 3 + width) 11 = 2 x width + 3 8 = 2 x width 4 = width So the width is 4in.


The length of a rectangle is 5 centimeters less than twice it's width The perimeter of the rectangle is 26 cm What are the dimensions of the rectangle?

Given: p = 26cm and 2x width - 5cm = length p = 2(a+b) = 26cm; a+b = 13cm 2x6-5=7 The sides of the rectangle are: width 6cm and length 7cm

If 15.6 and CE 4.5 what is the perimeter of the rectangle?

If the given dimensions are the length and width of a rectangle then its perimeter is 15.6+4.5+15.6+4.5 = 40.2


How do you find the length of a rectangle if the perimeter is 40 and the width is 2inches?

perimeter = 2 x (length + width) ⇒ length + width = perimeter ÷ 2 ⇒ length = (perimeter ÷ 2) - width So to find the length of the given rectangle, subtract the width from half the perimeter is how to do it. IF you meant "What is the length..." then: length = perimeter ÷ 2 - width = 40 ÷ 2 - 2 in = 20 - 2 in = 18 in

How can you calculate the length of a rectangle if the perimeter and the width are given?

Because the perimeter is lenght + length +width +width, you do perimeter - double the width, and then halve the remaining number. that should give you the length.


Find the perimemter of a rectangle with length 15 meters and width 10 meters?

The perimeter of a rectangle is given by:P = 2l + 2w, where P is the perimeter of the rectangle, l is the length of the rectangle, and w is the width of the rectangle.P = 2(15) + 2(10) = 50 meters.
