Question
The measurements of a rug are 3 cm by 4 cm. The area of a rug is ______________.
- 10 cm2
- 11 cm2
- 12 cm2
- 13 cm2
Hint:
The rug is of rectangular shape and the area will be equal to the product of length and breadth of the rug. The formula of the area of the rectangle is 
,where L is the length/base of the rectangle and B is the breadth/width of the rectangle.
The correct answer is: 12 cm2
The rug is of rectangular shape and the area will be equal to the product of length and breadth of the rug. The formula of the area of the rectangle is ,where L is the length/base of the rectangle and B is the breadth/width of the rectangle.
Step1: Given base = 
and width =
. Now we have to put it in the formula of the area of the rectangle to get the area.
Area =
Step2: Now we will calculate the area of the rectangle.
Area = 
Area = 
.
So, the area of the rectangle is .
