Question

The ratio of length and breadth of a room is 3:2.if the room is 12 m long find the breadth, perimeter and area of the room.

Answer 1

Answer:

Breadth = 8m

Perimeter = 40m

Area = 96m^2

Step-by-step explanation:

$\huge\mathbf\green{Question :-}$

The ratio of length and breadth of a room is 3:2.if the room is 12 m long find the breadth, perimeter and area of the room.

${\blue{\underline{\underline{\huge{\bold{Given:-}}}}}}$

Ratio of length and breadth of a room = 3:2

Length of a room = 12m

Let the length be 3x and breadth be 2x

=> 3x = 12m

=> x = 12/3m

=> x = 4m

Breadth = 2x = 2×4m = 8m .

Perimeter = 2(l+b) = 2(12+8)m = 2×20m =40m .

Area = l × b = 12m×8m = 96m^2 .

Answer 2

ANSWER:

• Perimeter of room = 40 m
• Area of room = 96 m²

GIVEN:

• Ratio of length and breadth of a room is 3:2.
• Length of room = 12 m.

TO FIND:

• Perimeter and area of the room.

SOLUTION:

Let the length and breadth be 3x and 2x.

According to Question:

=> 3x = 12

=> x = 12/3

=> x = 4 m

Breadth of room = 2x

= 2(4)

= 8 m

Perimeter of room = 2(length+Breadth)

= 2(12+8)

= 2(20)

= 40 m

Perimeter of room = 40 m

Area of room = (length)(Breadth)

= (12)(8)

= 96 m²

Area of room = 96 m²
