Area of rectangle having length 11 cm and breadth 11/2 cm is 121/2 cm² .
Given, that length of rectangle is double that of its width.
Area of rectangle = l × b
l = Length of rectangle .
b = Breadth of rectangle .
As length of rectangle is double of width.
Width = 11/2 cm
Length = 2 × (11/2) cm
Length = 11 cm
Substitute the values in the area formula,
Area of rectangle = l × b
Area of rectangle =
Area of rectangle =
Therefore the area of rectangle is .

The total area of the United State will be 3,537,438.
What is Addition?
The process of combining two or more numbers is called the Addition.
Given that;
The total land area of the United States is about 3,483,511 square miles more than the total land area of Tennessee, which is about 53,927 square miles.
Now,
Let the total area of the United State = x
Hence, We can formulate;
⇒ x = 3,483,511 + 53,927
⇒ x = 3,537,438
Thus, The total area of the United State = 3,537,438.
