Question

the length of the floor of a rectangular room is 14 metres and breadth is 12 metres .find the total expenditure of flooring the room at the rate of rupees 25 per square metre.​

Answer 1

AnswEr :

$\bold{Given} \begin{cases}\sf{Length=14 \:m} \\ \sf{Breadth=12 \:m}\\ \sf{Rate \:of \: Flooring=Rs. 25 \:@ {m}^{2} }\end{cases}$

⋆ Reference of Image is in the Diagram :

$\setlength{\unitlength}{1.5cm}\begin{picture}(8,2)\thicklines\put(7.7,3){\large{A}}\put(7.3,2){\mathsf{\large{12 m}}}\put(7.7,1){\large{B}}\put(9.2,0.7){\matsf{\large{14 m}}}\put(11.1,1){\large{C}}\put(8,1){\line(1,0){3}}\put(8,1){\line(0,2){2}}\put(11,1){\line(0,3){2}}\put(8,3){\line(3,0){3}}\put(11.1,3){\large{D}}\end{picture}$

• CALCULATION OF AREA OF FLOOR :

$\longrightarrow \tt Area \:of \: Floor = Length \times Breadth \\ \\\longrightarrow \tt Area \:of \: Floor = 14m \times 12m \\ \\\longrightarrow \blue{\tt Area \:of \: Floor = 168 \: {m}^{2}}$

$\rule{300}{1}$

• CALCULATION OF EXPENSE :

$\implies \tt Expenditure = Area \: of \:Floor \times Rate \\ \\\implies \tt Expenditure = 168 \times Rs.25 \\ \\\implies \boxed{\orange{\tt Expenditure = Rs. \:4200}}$

⠀

∴ Expenditure on Flooring is Rs. 4200

$\rule{300}{2}$

$\star \: \underline\frak{Some \: Information \: About \:Rectangle :}$

⋆ Opposite sides are equal and parallel.

⋆ All angles are equal to 90 degrees.

⋆ The diagonals are equal and bisect each other.

⋆ The intersection of the diagonals is the circumcentre. That is you can draw a circle with that as centre to pass through the four corners.

⋆ Any two adjacent angles add up to 180 degrees.

⋆ Lines joining the mid points of the sides of a rectangle in an order form a rhombus of half the area of the rectangle.

⋆ The sum of the four exterior angles is 4 right angles.

⋆ Area of Rectangle = Length * Breadth

⋆ Perimeter of Rectangle = 2*(Length + Breadth)

Answer 2

Answer:

$\huge\underline\mathfrak{\sf{Answer\::}}$

$\textbf{\underline{Given\::}}$

● Length of the floor= 14 m

● Breadth of the floor = 12 m

● Rate = 25 per sq.m

$\textbf{\underline{To\:find\::}}$

● Expenditure of flooring the room

$\textbf{\underline{Solution\::}}$

Area = Length × Breadth

=> Area = (14 × 12) sq.m

=> Area = 168 sq.m

$\rule{300}{2}$

Expenditure = Area × Rate

=> Expenditure =Rs. (168 × 25)

=>Expenditure =Rs.4200

$\rule{300}{2}$
