Answer 1

To find the perimeter of a square field with an area of 256m², you can find its side length by taking the square root of the area and then calculate the perimeter by multiplying the side length by 4. If the perimeter of a square sheet of paper is 52cm, you can find the area by squaring the length of one side, which is found by dividing the perimeter by 4. If the area of a square sheet of paper is 144cm², you can find the side length by taking the square root of the area and then calculate the perimeter by multiplying the side length by 4.

Step-by-step explanation:

The area of a square field

To find the perimeter of a square, you multiply the length of one side by 4. So, if the area of a square field is 256m², you can find its side length by taking the square root of the area. In this case, the side length would be 16m. Therefore, the perimeter of the square field would be 4 times the side length, which is 64m.

The area of a square sheet of paper

If the perimeter of a square sheet of paper is 52cm, you can find the length of one side by dividing the perimeter by 4. In this case, the side length would be 13cm. To find the area of a square, you square the length of one side. So, the area of the square sheet of paper would be 13cm multiplied by 13cm, which is 169cm².

The area of a square sheet of paper

If the area of a square sheet of paper is 144cm², you can find the length of one side by taking the square root of the area. In this case, the side length would be 12cm. To find the perimeter of a square, you multiply the length of one side by 4. So, the perimeter of the square sheet of paper would be 12cm multiplied by 4, which is 48cm.
