PLEASE ANSWER!! What is the length of one side of a square that has an area of 289 in(a small 2 at the end)

Question

What is the length of one side of a square that has an area of 289 in(a small 2 at the end)

a. 7

b. 14

c. 17

d. 27

Answer 1

Multiply each of those by itself and see which one equals 289.

Answer 2

c.17

because the square root of 289 is 17

[17 x 17 = 289]

=)

Answer 3

17

17 by 17 would be 289

Answer 4

There are two ways to do this problem. If you like to rule out answers by using them or plugging them in, then you can just take each answer choice and square it to see which one gives you 289. (We do this because the area of a square is the length of a side times the length of a side, or "side squared." You will get answer choice c because 17 squared is 289.

You could also start out with a formula you already know. the area of a square is "side squared," so in this case 289=side squared. then, to get the length of a side by itself, we need to take the square root of each side. this will give you the square root of 289 which is 17.

Answer 5

Area of a square = length^2

289 = length^2

length = root of 289

length = 17

Answer 6

Hint small 2 means square
