Question

A room is 26 m long and 15 m wide. A 14 m
square carpet is laid on the floor. What area is
not carpeted?​

Answer 1

Answer:

194m²

Step-by-step explanation:

Area of room = 26 ×15 m² = 390m²

Area of square carpet = 14×14 m² = 196m²

Area not carpeted = 390 - 196 m²

= 194m²

Answer 2

Answer:

194 m²       You might think -"But, how?"

Step-by-step explanation:

Area of the room which is not carpeted = 194 m²

Dimensions of a room:

Length (L)=26 m,

Width (W) = 15 m

Dimensions of a square carpet :

Length of the edge (a) = 14 m

Area of the room not carpeted =

Area of the room - Area of the carpet

=> L × W - a²

=> 26 m × 15 m - (14 m)²

=> 390 m² - 196 m²

=> 194 m²

Therefore,

Area of the room which is not carpeted = 194 m²
