Question
Find the area of the given rectangle. Each unit square represents one centimeter
- 10 square cm
- 21 cm
- 10 cm
- 21 square cm
Hint:
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: 21 square cm
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 length = 
and width = 
. Now we have to put it in the formula of the area of the rectangle to get the area. In the diagram there is given small squares of unit area, i.e., area = 
.
Area =
Step2: Now we will calculate the area of the rectangle.
Area = 
Area = 
.
So, the area of the rectangle is .
