Asquare has an apothem measuring 2.5 cm and a perimeter of 20 cm. what is the area of the square, rounded to the nearest square centimeter? 13 cm2 25 cm2 50 cm2 100 cm2

The answer would be 25cm2 Because it gives you the perimeter of 20. Since you know that to get perimeter you add up all the sides of the shape, you can do 20/4 to reverse the perimeter, then you figure out that one side length is 5cm. Knowing that, you can use the area formula of a square and do 5 x 5 to get the area of 25cm2.

Hope this helped :)

You would have to multiply all of the numbers
