Why is the perimeter of rectangle with an even width and lenght always an even number?
If both numbers are even, it will always be an even number. For example, 2 + 2 = 4.
A group of students are finding the perimeters of rectangles whose lengths and widths are whole numbers they notice that all the perimeters are not even numbers is this always true?
No, it is always false. Perimeter of a rectangle= 2l + 2w, l= length, w=width. 2*any whole number, regardless odd or even, is even. Thus 2l is even and 2w is even. The sum of two even numbers is always even.
