What is the length and width of a rectangle with a perimeter of 48?

Now, the perimeter of the rectangle =48 . ∴w=8,&,so,l=2w=16 inches.

How do you get the length of a rectangle with the perimeter?

If the perimeter and the length of a rectangle are known, the width = P/2 – l, where l = length, w = width, and P = perimeter of the rectangle. If the perimeter and the width are known, Length(L) = P/2 – w.

Is it length by width or width by length?

In general length is bigger than width. So first you write “length” and then “width”. But there is no fixed rule, this is just for convenience.

Is the length of a rectangle double its width?

SOLUTION: the length of a rectangle is double its width. if a rectangle has a perimeter of 48 cm, (find in cm) its length. Question 299692: the length of a rectangle is double its width. if a rectangle has a perimeter of 48 cm, (find in cm) its length.

How do you find the length of a rectangle with perimeter?

Let l = the length of the given rectangle. Let w = the width of the given rectangle. Let l = the length of the given rectangle. If we name the width of the rectangle x, then its length is 2 x, so the perimeter can be expressed as x + 2 x + x + 2 x = 6 x = 48 c m ⇒ x = 8 c m So the length is 2 x = 16 c m.

What is the distance around a rectangle called?

The distance around a rectangle is called the perimeter of the rectangle. It is usually denoted by P P. To find the perimeter of rectangle we add the lengths of its sides. Thus, the perimeter of a rectangle with the length of a a and the width of b b is

How to find the dimensions of the rectangle 45cm2?

Before we can find the dimensions of the rectangle, we need find w first. Here’s how: 1) Write an equation that relates 45cm2, w+4 and w. To do so, we know that the area of the rectangle, 45cm 2 can be found by multiplying w with w+4. Hence, we have: To continue, we need to remove the bracket and simplify the equation.
