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 cm225 cm250 cm2100 cm2

We can find the side of a square in two different ways:

Using the perimeter:

Using the apothem:

Where,

P: Perimeter of the square

a: apothema of the square

L: square side

Using the perimeter we have:

Using the apothem we have:

We observe that both results are the same

Then, the area of the square is:

the area of the square is:

a

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
