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.

What are the lengths of the sides of 3 rectangles with a perimeter of 12 units only whole numbers?

Perimeter = 2 x (width + length)⇒ 12 = 2 x (width + length)⇒ width + length = 6⇒ the rectangles could be:1 by 52 by 43 by 3[A square is a rectangle with equal sides.]

How do you draw all possible rectangles with a perimeter of 36cm and sides whose lengths are whole numbers?

Draw nine rectangles, with the following dimensions:1 by 172 by 163 by 154 by 145 by 136 by 127 by 118 by 109 by 9If you want to get the jump on the next topic coming up in math, thenwhile you're drawing these rectangles, notice that even though theyall have the same perimeter, they all have different areas.


Two rectangles have the same area 480m2 The difference in their lengths is 10m The difference in their widths is 4m Determine the lengths?

I would list all the factors of 480 (as pairs of numbers whose product is 480). Then find two pairs of numbers (L1,W1 and L2,W2) satisfying these properties. (It won't take long, since there are at most sqrt(480) (rounded down) pairs of numbers whose product is 480, ie. just try the numbers 1,2,3,...,21.) Hope that helps!
