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.

The perimeter of a rectangle is always even because the perimeter is twice the length plus twice the width. Whenever you multiply a number by 2, the product is even. When you add two even numbers the sum is even.

Yes, the perimeter or area of a rectangle can be an irrational number. Thanks

A rectangle whose opposite sides are 4 cm and 2.5 cm. Its perimeter is 2*(4 + 2.5) = 2*6.5) = 13 cm.

A 6 by 4 rectangle will have a perimeter of 20 units

To find the width of a rectangle, multiply the lenght by 2 and subtract it from the perimeter. Once this is done you are left with the two width sides of the rectangle. To find the width divide this number by 2 and you have your answer. For exaple: P= 120 cm L= 40 cm L* 2 = 80 120 - 80 = 40 40/2 = 20 W=20

Type your answer here... give the dimensions of the rectangle with an are of 100 square units and whole number side lengths that has the largest perimeter and the smallest perimeter

the old perimeter is 17 * 2 The old perimeter = 38

You multiply the length by 2 (because there are two sides of the rectangle that have that measure). You then subtract that number from the perimeter. The number you will be left with is twice the width, so you divide that by two and you get the width of the rectangle.

There is no relationship between the perimeter and area of a rectangle. Knowing the perimeter, it's not possible to find the area. If you pick a number for the perimeter, there are an infinite number of rectangles with different areas that all have that perimeter. Knowing the area, it's not possible to find the perimeter. If you pick a number for the area, there are an infinite number of rectangles with different perimeters that all have that area.

the answer to number 20 is B...12

Since the only number given in the question is a linear measure, it must refer to the perimeter of the rectangle: it cannot refer to its area. So, number of feet of fencing required to enclose a rectangle with a 44 ft perimeter is 44 ft! That is what a perimeter means!

You cannot find the perimeter unless the rectangle is a regular rectangle (a square) in which case the perimeter is 4 times the square root of the area. With just the area the shape of the rectangle could be any number of shapes with different perimeter, for example, imagine 6 square units 1cm by 1cm arranged in a 1*6 configuration to give a long thin rectangle, the perimeter would be 6+6+1+1=14cm, the same 6 arranged in a 3*2 rectangle would have the same area, but a perimeter of 3+3+2+2=10cm, for this reason a rectangle's perimeter cannot be determined from the area alone.

18cm is the area and perimeter. the width is 3cm.

If you are given the area you will have to think what do you times with the number you have to get it.

If the length and width of a rectangle are multiplied by the same number, then . . . -- the perimeter is multiplied by the same number -- the area is multiplied by the square of the numbner

It is 5 units * 20 units. A smaller perimeter can be attained by a square but the question specified a rectangle.

In order to know the perimeter of a rectangle, you need to know both its length and its width ... two numbers. One number isn't enough. If one side of a rectangle is 22 feet, then the perimeter of the rectangle can be any number greater than 44 feet. There are an infinite number of different possibilities.

Yes, of course. Why ever not ? You can make your rectangle any size you want.

Any number between 0 and 12 that you like. There is no need for the sides of the rectangle to be whole numbers!

It is not possible to answer the question because you have not defined what 32 measures: is it the area of the rectangle, its perimeter, its diagonal or some other property?

24 feet square feet

Perimeter: 18 Area: 10 sq units

Yes, if the sides are 4 units.
