A rectangle whose opposite sides are 4 cm and 2.5 cm. Its perimeter is 2*(4 + 2.5) = 2*6.5) = 13 cm.
No. One length could be 3 and the others three of a triangle. The total perimeter is 9 units, which is an odd number.
not always. nothing can be generalized about the sum of two irrational number. counter example. x=(sqrt(2) + 1), y=(1 - sqrt20) then x + y = 1, rational.
Not always as for example 36 is a multiple of 4 but not of 8
negative Example would be. 0.1x0.1=0.01
No, a GCF is not always great than one. For example the GCF of 7 and 3 is 1.
To answer this simply try a few out for yourself. In a 2x1 cm rectangle, the area is 2 cm squared and the perimeter is 6 cm In a 12x10 rectangle, the area is 120 cm squared and the perimeter is 44 cm. In some cases, the perimeter is larger and in others it is smaller. To answer your question, no, the perimeter of a rectangle is NOT always greater than its area.
For a fixed perimeter, the area will always be the same, regardless of how you describe the rectangle.
If both numbers are even, it will always be an even number. For example, 2 + 2 = 4.
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.
No. A rectangle of 1 x 3 has the same perimeter as a rectangle of 2 x 2, but the areas are different.
If you increase the rectangle's length by a value, its perimeter increases by twice that value. If you increase the rectangle's width by a value, its perimeter increases by twice that value. (A rectangle is defined by its length and width, and opposite sides of a rectangle are the same length. The lines always meet at their endpoints at 90° angles.)
A rectangle is always a quadrilateral and a parallelogram.
No, any shape with four sides and same perimeter will always be a square.
no because one rectangle may be 3x4 which the perimeter is 14 and one rectangle may be 5x2 which as well equals 14
Not always because a 2 by 12 rectangle will have the same area as a 4 by 6 rectangle but they both will have different perimeters.
a parallelogram is always a example of a rectangle a rhombuz and a trapezoid
A quadrilateral polygon
