Question

the area of the four walls of a room is 280
CM square if the length and height of the room at 22 M and 3.5m respectively find the breadth of the room​

Answer 1

Answer:

• 18m is the required breadth of the room.

Step-by-step explanation:

According to the Question

It is given that ,

• Area of four walls 280cm²
• Length ,l = 22m
• Height ,h = 3.5

we have to calculate the breadth of the room.

Let the breadth of the room is b

As we know,

• Area of Four Walls = 2 (l+b)h

substituting the value we get

↠ 2 (22+b) × 3.5 = 280

↠ 7 (22+b) = 280

↠ 22 + b = 280/7

↠ 22 + b = 40

↠ b = 40 - 22

↠ b = 18

• Hence, the breadth of the room is 18 m.
