<h3>Explanation:</h3>
We have to find the area of the square shaped room.
<h3>Given:</h3>
Side of the square shaped room = 10 m
The cost of flooring a square metre is Rs. 50
<h3>To Find:</h3>
The cost of flooring a square shaped room.
<h3>Formula:</h3>
Area of square = Side × Side
<h3>Solution:</h3>
Area of the square = 10 × 10 = 100 sq.m
1 sq.m = Rs. 50
100 sq.m = 50(100) = Rs. 5,000
<h2>Answer:</h2>
The cost of flooring a square shaped room of side 10 m is <u>Rs. 5,000</u><u>.</u>
Answer:

Step-by-step explanation:
stupid enough
y=mx+b

slope = 16-12/3-6
-4/3

plug in x and y
16=-4/3(3)+b
b=20

Answer:
Alicia is 18years
Quentin is 14years
Rosalyn is 16years
Step-by-step explanation:
Let the age of Alicia be x
Let the age of Quentin be y
Let the age of Rosalyn be z
If the sum of the siblings’ ages, in years, is 48 then;
x+y+z = 48.... 1
If Rosalyn is two years older than Quentin then;
z =y+2 ..... 2
Also if Quentin is four years younger than Alicia then;
y = x-4 ... 3
From 3:
x = y+4 ... 4
Substitute 2 and 4 into 1 to have:
y+4+y+y+2 = 48
3y + 6= 48
3y = 48-6
3y= 42
y = 14
Since x= y+4
x = 14+4
x = 18
Since z = y+2
z = 14+2
z = 16year
This means that;
Alicia is 18years
Quentin is 14years
Rosalyn is 16years
