The length of an Aluminium strip is $40 c m$ . If the lengths in cm are measured in natural numbers, write the measurement of all the possible rectangular frames which can be made out of it. (For example, a rectangular frame with $15 c m$ length and $5 c m$ breadth can be made from this strip.)

Solution

Perimeter of rectangular frame $=$ Length of the aluminium strip
$\Rightarrow 2 \times (l e n g t h + b r e a d t h) = 2 \times (15 + 5) = 40 c m$ .
