Area and Perimeter of a Rectangle

Problem Description

The first lesson on structs: define a struct, access its members.

A struct packs several related values into a single object. Define a struct that represents a rectangle:

struct Rectangle {
    int a;  // length
    int b;  // width
};

Read the length and width of $n$ rectangles into struct variables, then print each rectangle's area ($a \times b$) and perimeter ($2(a+b)$). Access the members with .a and .b.

Input Format

The first line contains a positive integer $n$; the next $n$ lines each contain two integers $a, b$, the length and width of one rectangle.

Output Format

$n$ lines; line $i$ holds the area and the perimeter of the $i$-th rectangle, separated by a space.

Sample Input

2
2 3
5 1

Sample Output

6 10
5 12

Constraints

For 100% of the test data, $1 \le n \le 100$ and $1 \le a, b \le 1000$.

Hint: this problem tests defining a struct and accessing its members — really define the struct, do not dodge it.
