Question

how to draw a rectangle of side 7cm and area 36sqcm

Answer 1

take the breath as 5.14 approx cm and length as 7cm. the area thus formed of the rectangle would 36sqcm

Answer 2

If one side is 7cm and the area is 36 cmsq, then the other side must be 36/7 = 5.1428...
(area of a rectangle = length × width)

So draw a rectangle with one side 7 cm and the other being 5.1 cm.

7 × 5.1 is approximately 36

You cannot draw 5.14 cm with a scale and your hand, so draw it 5.1 cm.
