Question

If p squares of each site $$1\, mm$$ makes a square of side $$1\, cm$$, then p is equal to.

Answer 1

Correct option is B. $$100 $$
Option (b) is correct.
Since, area of one square having side of $$1\, mm$$
$$= 1\times 1\, mm^2=1\, mm^2$$
Area of the square having side of $$1\, cm$$
$$\Rightarrow p \times 1\, mm^2 = 1\, cm^2$$
$$\Rightarrow p \, mm^2 = (10\, mm)^2$$
$$\Rightarrow p\, mm^2= 100\, mm^2$$
$$\Rightarrow p= 100$$
