Answer 1

Answer:

$\sf \underline \blue{Given : }$

• The dimensions of room are 24m × 14m.If a border with tiles 1 sq M are laid on all along its sides,then find the number of such tiles needed.

$\sf \underline \blue{To \: Find : }$

• find the number of such tiles needed.

$\sf \underline \blue{Solution : }$

Area of floor = 14 × 26

$\sf \boxed{ \pink \leadsto \: 336 {m}^{2} }$

A border with tiles 1 sq M are laid on all along its sides,

Remain size after laying tiles.

$\sf \boxed{ \blue =14 - 1 - 1 \:and \: 24 - 1 - 1 }$

$\mathbb{ = 12 \: and \: 22m}$

•°•Area of floor including border = 12 × 22

$\sf \boxed{ = 264 {m}^{2} }$

•°•Area of border = 336 - 264

$\sf \boxed{ = 72 {m}^{2} }$

Area of a tile = 1 × 1 = 1 m²

Number of tiles required

$\sf \red{ \leadsto \frac{72}{1} = 72 }$

$\sf \boxed { \purple \leadsto \: 72 \: Tiles \: needed }$
