${\huge{\rm{\underline{\underline{Question :-}}}}}$

Q)) A room is 4m long and 3m 50cm wide . How Many square meter of carpet is needed to cover the floor ?

${\huge{\underbrace{\rm{Answer\checkmark}}}}$

$\frak{Given}\begin{cases}\rm{Length\:of \:room=\bf{4\:m.}}\\ \rm{Breadth\:of\:room=\bf{3\:m\;50\:cm.}}\\ \rm{We\:are\:\bf{carpeting}\:the\:floor.}\end{cases}$

${\large{\underline{\rm\maltese\:To\:Find:}}}$

• The area to be carpeted .

${\large{\underline{\rm\maltese\:Solution:}}}$

We have -

• Length = 4 m

and

• Breadth = 3m 50cm = 3.50 m

As , the floor is rectangular so,

$\colon \implies \sf \: area _{ \: ( \: carpeted \: )} = length \times breadth \\ \\ \colon \implies \sf \: area _{ \: ( \: carpeted \: )} = 4\times 3.50 \: {m}^{2} \\ \\ \colon \implies \: \underline{ \boxed{ \tt{ area _{ \: ( \: carpeted \: )} = \bf \pink{ 14 \: {m}^{2} }}}}$

So ,

14 m² of carpet is needed to cover the floor .

★ More about rectangle :

• Rectangle is a quadrilateral i.e. it has four sides.

• Opposite sides in rectangle are equal and parallel.

• All the angles in a rectangle are equal to 90° .

• Perimeter = 2(length×breadth) .

• Area = length × breadth.
