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.
Why is the perimeter of a rectangle always even?
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.
Can the perimeter or area of a rectangle ever be an irrational number?
Yes, the perimeter or area of a rectangle can be an irrational number. Thanks
Can you give a counter example to show that a rectangle does not always have a perimeter which is not an even number?
A rectangle whose opposite sides are 4 cm and 2.5 cm. Its perimeter is 2*(4 + 2.5) = 2*6.5) = 13 cm.
How can you get a rectangle with whole-number side length's and a perimeter of 20 meters?
A 6 by 4 rectangle will have a perimeter of 20 units
How do I find the width of a rectangle if I know its length and its perimeter?
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
What is the relationship for perimeter and area for 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.

What happens to the perimeter and the area of a rectangle if the length and the width are multiplied by the same number Use diagrams to explain?
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
Rectangle has whole number side lengths the length of the rectangle is tripled and the width is doubled The new area is 204 cm squared. The new perimeter is 110 cm. What was the old perimeter?
the old perimeter is 17 * 2 The old perimeter = 38
How many feet of fencing do you need to enclose a 44 ft rectangle?
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!
