Answer 2

Appropriate Question :

• If length, breadth and height of a room are 8cm, 6cm and 10cm respectively. find area of four walls.

Answer :

• Area of four walls = 280cm²

Given :

• Length, breadth and height of a room are 8cm,6cm and 10cm

To find :

• Area of four walls

Solution :

Given,

• Length of a room = 8cm
• Breadth of a room = 6cm
• Height of a room = 10cm

We know that,

• Area of four walls = 2(l + b)h

Where,

• l is a Length of a room
• b is breadth of a room
• h is height of a room

Substituting the value :

⤍ Area of four walls = 2(l + b)h

⤍ Area of four walls = 2(8 + 6) × 10

⤍ Area of four walls = 2(14) × 10

⤍ Area of four walls = 28 × 10

⤍ Area of four walls = 280 cm²

Hence,

Area of four walls = 280cm².
