Question

plzzzzzzzzz solve it . it is urgent​

Answer 1

Answer:

16875 rupees

Step-by-step explanation:

LET THE LENGHT BE x m .

AREA OF 1 WALL = x * x / 3 = x ^ 2 / 3 .

AREA OF CEILING = x ^ 2

AREA OF PLASTERING = 4 ( x ^ 2 / 3 ) + x ^ 2 = 7 * x ^ 2 / 3

7 * x ^ 2 / 3 * 8.4 = 4410

x = 15

AREA OF FLOOR = x ^ 2 = 225

COST OF CARPETING = 225 * 75 = 16875

Answer 2

Answer: 15*15*75=16875/-

Step-by-step explanation:

Length=L

Height=L/3

Breath=L

Area of the side surfaces  = 4(L^2/3) [ area of the side surface=L*L/3, and 4 surfaces are there]

further, area of the ceiling = L^2, as ceiling is also square.

therefore, total area ,i.e., 4 wall surface area+ ceiling= 4(L^2/3)+L^2=7(L^2/3).

cost of painting Rs.36 per sq.m and total amount spent=18900/-

therefore, length= 36*7(L^2/3)=18900

or L= 15.

therefore, total amount to be spent at per 75 Rs/Sq. m for carpeting the whole floor is Rs. 15*15*75=16875/-
