Best Answer

Dimensions are given out as length by width

14cm by 1cm

13cm by 2cm

12cm by 3cm

11cm by 4cm

10cm by 5cm

9cm by 6cm

8cm by 7cm

And the rest is all repeats of the above.

Q: What are all the possible rectangles with a perimeter of 30cm 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.

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.]

The answer is, you can draw a rectangle with these measurements: 6cm and 9cm 5cm and 10cm 7cm and 8cm

No, take the rectangle that is 4x6. The perimeter is 20 which is even.

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.]

If those numbers are the lengths of the sides, just add them.

Find the lengths of the sides, and add up the three numbers.

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.
