Raju sprayed a square carpet of side 4 metre in a square room of side 6 m how much area will be left in the room without carpet
Answers
Sides of the carpet (a) = 4m
Therefore, area of the carpet = (a)²
= (4m × 4m)
= 16m²
Now, sides of room (A) = 6m
Therefore, area of room = (A)²
= (6m × 6m)
= 36m²
Leftover portion of the room = {(A)² - (a)²}
= {36m² - 16m²}
= 20m²
Hence, area of the leftover portion of the room = 20m²
Given - Side of carpet and room
Find - Area left without carpet
Solution - Area of carpet = side²
Area of carpet = 4²
Taking square
Area of carpet = 16 m²
Area of room = side²
Area of room = 6²
Taking square
Area of room = 36 m²
Area of room left uncovered = 36 - 16
Performing substraction to find the area of room left uncovered
Area of room left uncovered = 20 m².
Therefore, the area of room without carpet is 20 m².
