What will be the area of the square garden when its perimeter is 10 km?
If the perimeter of a square garden is 10 km. Then each side will 10/4, since perimeter of a square is P = 4*s. So each side will be 2.5 km in length.The area of the square garden will be (side)2 . So the area of the garden will be (2.5 km)2 or 6.25 km2

What has an area of 1 km2?
Anything two dimensional whose dimensions equate to an area of 1 Km2. It depends on the shape of the specific object in question as to how we calculate area, but to keep things simple let's look at a rectangle. A rectangle's area is simply its length multiplied by its width. So: For example a perfectly flat rectangular field with dimensions 1 Km by 1 Km would have an area (surface area) of 1 Km2. (1 * 1 = 1) Equally, if the dimensions of the field were 0.5 Km by 2 Km then the area would also be 1 Km2. (0.5 * 2 = 1)
