Question

The perimeter of a square field is 1.6 kilometers. What is the area of the field in square kilometers

Answer 1

For a square with side length L, the perimeter P is\[P=4L\] The area A is \[A = L^{2}\]Then the area in terms of the perimeter is \[A = \frac{ P^{2} }{ 16 }\]

Answer 2

I don't get that

Answer 3

The last formula has both the area and perimeter in it, so all you need to do is substitute values and solve.
