Question #71f34

Answer 1

`8.8` m

Explanation:

Since the area of a square is `l^2` where `l` represents the width of the square, we can reverse the operation to obtain the length given the area. Therefore:

`l^2 = 4.84`
`l = sqrt(4.84) = 2.2`

Note that we ignore the negative values of the square root as width cannot be negative, since `(2.2)^2` and `(-2.2)^2` yield the same result.

Now that we have the width of the square, we know that the perimeter would be `4l`, or four times the length. Therefore,

`4l = 4 * 2.2 =8.8`

Thus the perimeter of the crime scene is `8.8` m.

Note: Don't forget units!
