Question

The area of a square is 42.25 metre square. find the side of the square. if the tiles measuring 13 cm into 13 cm are paved on the square area, find how many tiles are used for paving it ?​

Answer 1

$\sf\boxed{\underline{\huge{\rm{Question:}}}}$

The area of a square is 42.25 m²:

(i) Find the side of the square.

(ii) If the tiles measuring 13 cm × 13 cm are paved on the squared area, find how many tiles are used for paving it.

$\sf\boxed{\underline{\huge{\rm{Solution:}}}}$

Given:

Area of the square = $\rm{42.25 m^2}$

(i) Area of the square = $\rm{side^2}$,

⇒side = $\sf\sqrt{42.25}m$

⇒side = $\sf{6.5 × 100 cm = 650 cm}$

(ii) Number of tiles required

$=\rm\dfrac{Area\:of\:the\: square}{Area\:of\:one\: tile}=\dfrac{650×650}{13×13}=2500$
