If the perimeter of a square is 28 inches what is its area

49 in²

Step-by-step explanation:

If the perimeter is 28, that means each side is 7 inches. This is because a square has 4 equal sides and 28 ÷ 4 = 7.

The area is found by multiplying two of the squares sides together, 7 x 7 = 49.

other answer is correct. i had used the radius of the radius somehow. a website:

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
