Final answer:
The perimeter and area of a star from 1 cm grid paper cannot be given exactly without a visual. For a regular five-pointed star, you can approximate the perimeter by summing the lengths of sides and the area by counting full and partial grid squares it covers.
Step-by-step explanation:
The question regarding the perimeter and area of a star cut from 1 cm grid paper is a problem in geometry, a branch of mathematics. Without a visual representation of the star, providing an exact perimeter and area is not possible. However, you can approximate the perimeter by counting the number of grid sides the star spans and the area by counting the number of fully enclosed squares within the star plus estimating the area of partial squares.
If you are dealing with a regular five-pointed star, and the star spans a 1 cm grid, the perimeter would be approximately equal to the sum of the lengths of the sides of the star. As for the area, you would count the number of full squares it covers on the grid and add an approximation of the partial squares. For example, if the star fully covers 5 squares and partially covers an additional 10 with approximately half of each being covered, you would calculate the area as 5 + (10 * 1/2) = 10 square centimeters.
