When measuring linear meters of a product with a width, one ignores the width and measures the length as it comes off the role. Therefore 30 cm length is the sames a 0.3 linear meters. However, 30 cm x 30 cm, as specified in the question, is a measure of area and it makes no sense to try and convert an area into a length (linear measure).
If the perimeter is 32 sq cm, there is a very serious problem since the perimeter is a linear measure, not an area! Leaving that aside, the length of the rectangle is 10 cm and the breadth is 6 cm.
A linear length of 1 cm has no width so its area is 1 x 0 = 0 sq cm
There are 2.54 cm in 1 inch, so 115 inches = 115 x 2.54 cm = 292.1 cmAlgebraic Steps / Dimensional Analysis Formula115 in*2.54 cm1 in=292.1 cm
The area of 23cm by 5cm is 115 square cm.
