I'm going to refer to the length of the pool as L.
2x + 2L = perimeter.
The width of pool multiplied by two added to the length of the pool multiplied by two equals to the perimeter.
Answer:
35y2+13y−12
=35y2+28y−15y−12
=7y(5y+4)−3(5y+4)
=(7y−3)(5y+4)
Therefore, the possible length and breadth are 7y-3 units and 5y+4 units
Those are a lot of problems. Sorry I can't help you because I can't really see them.
30% is 24
45% is 36
take 15% and multiply it by however much it takes to make the percentage than multiply that by 12
