The perimeter of a square is 52 cm.
Calculate the area of the square.

169 cm²

Step-by-step explanation: Remember that the formula

for the perimeter of a square is 4 times a side.

Therefore, since the perimeter of the given square is 52,

we have 52 = 4s and dividing both sides by 4, 13 = s.

Now, remember that the formula for the area of a square is s² and since

the length of a side of a given square is 13, we have (13)² or 169.

So the area of a square that has a perimeter of 52 cm is 169 cm².

Notice that we include square centimeters in our final answer because

we were given centimeters as our units in the original problem.

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
