1.	A room has a floor area of 15 m by 10 m. A square carpet of side 7 m is laid on the floor. How much of the floor area is not carpeted?
Answer» Answer: 101 m² is the REQUIRED answer Step-by-step explanation: According to the Question It is given that , Length of ROOM ,l = 15m Breadth of Room ,B = 10m and, Side of Square carpet ,s = 7m we have to calculate the floor area which is not carpeted . So, FIRSTLY we calculate the floor area of room . Area of Floor = Length × breadth substitute the value we get ➻ Area of floor = 15×10 ➻ Area of floor = 150m² Now, calculating the area of carpet . Area of Carpet = Side × Side Substitute the value we get ➻ Area of Carpet = 7×7 ➻ Area of Carpet = 49m² Area which is not carpeted by the carpet will be = Area of floor - Area of Carpet = 150m² - 49m² = 101m² Hence, the area which is not carpeted will be 101 m²

Answer:

Step-by-step explanation:

According to the Question

It is given that ,

and,

we have to calculate the floor area which is not carpeted .

So, FIRSTLY we calculate the floor area of room .

substitute the value we get

➻ Area of floor = 15×10

➻ Area of floor = 150m²

Now, calculating the area of carpet .

Substitute the value we get

➻ Area of Carpet = 7×7

➻ Area of Carpet = 49m²

Area which is not carpeted by the carpet will be

= Area of floor - Area of Carpet

= 150m² - 49m²

= 101m²

Hence, the area which is not carpeted will be 101 m²
