## Problem: Change Tiles

The tiles on the ground in front of an apartment building need changing. The ground has a square shape with side N metres. The tiles are wide "W" metres and long "L" metres. There is one bench on the ground with width M metres and length O metres. The tiles under it are not necessary to be replaced. Each tile is replaced for 0.2 minutes.

Write a program that reads the size of the ground, the tiles and the bench from the console, and calculates how many tiles are necessary to cover the ground and the total time for replacing the tiles.

Example: ground with size 20 m. has аrea 400 sq.m.. A bench that is 1 m. wide and 2 m. long, has area of 2 sq.m.. One tile is 5 m. wide, 4 m. long and has area of 20 sq.m.. The space that needs to be covered is 400 – 2 = 398 sq.m.. 398 / 20 = 19.90 tiles are necessary. The time needed is 19.90 0.2 = 3.98 minutes.*

### Input Data

5 numbers are read from the console:

• N – length of a size from the ground in the range of [1 … 100].
• W – width per tile in the range of [0.1 … 10.00].
• L – length per tile in the range of [0.1 … 10.00].
• М – width of the bench in the range of [0 … 10].
• О – length of the bench in the range of [0 … 10].

### Output Data

Print on the console two numbers: number of necessary tiles for the repair and the total time for changing them, each on a new line.

### Sample Input and Output

Input Output
20
5
4
1
2
19.9
3.98

Explanation of the example:

• Total area = 20 * 20 = 400.
• Area of the bench = 1 * 2 = 2.
• Area for covering = 400 – 2 = 398.
• Area of tiles = 5 * 4 = 20.
• Necessary tiles = 398 \/ 20 = 19.9.
• Necessary time = 19.9 * 0.2 = 3.98.
