The answer is 8. Wolfram|Alpha is great for these kinds of questions. Go to http://www.wolframalpha.com/ and math-y classes are much easier tbh
Hi
9k^2 + 24k + 16
= ( 3k + 4)(3k + 4)
Good luck
Step-by-step explanation:
From the given question it appears that (n-1) is in the numerator's place, if it is so, then let us solve it.

The answer would be 64 m2 because it said the length is the same as width so it is basically like a square. The perimeter is 32/4=8 because there are 4 sides in the rectangle. 8 times 8 is 64
The answer is 64 m2
