5x = length
4x = width
324 = perimeter
formula: P = 2(length) + 2(width)
324 = 2(5x) + 2(4x)
324 = 10x + 8x
324 = 18x
18 = x
Substitute the value of x = 18
Length = 5x = 5(18) = 90meters
Width = 4x = 4(18) = 72meters
X57 I think no just doing this for points so made a random number lol
The answer is A,

. This is because when plugging in -2 for x, the expression will look like this:

. To make the exponent positive, you have to flip it into a fraction. Then it will be

. Lastly, you simplify the denominator into 81.
