Question
Ms.Marble is deciding between rug A and rug B for her dining room. Each box equals 1 square foot.
Ring ‘A’ area is __________ greater than Ring ‘B’ area.
- 2 square feet
- 4 square feet
- 8 square feet
- 16 square feet
Hint:
In this question we have to calculate the area of each rug and then compare them. The area of individual rug will be equal to the product of rows and columns.
The correct answer is: 4 square feet
In this question we have to calculate the area of each rug and then compare them. The area of individual rug will be equal to the 
where R is the total number of rows and C is the total number of columns. In the diagram there is given small squares of unit area, i.e., area = 
Step1: Calculating the area of the rug.
Rug A
Here we are given the total number of rows are 
and the total number of columns are 
. So, the area will be equal to
Area =
Area = 
=>
Rug B
Here we are given the total number of rows are and the total number of columns are . So, the area will be equal to
Area =
Area = 
=>
So, the area of Rug B is 
more than the area of Rug A.
