<span>Perimeter of rectangle=2(l+b)
2(l+b)=74
(l+b)=37 l=37-b
Area of rectangle=l*b
330=l*b
330=(37-b)b
330=37b-b^2
b^2-37b+300=0
By solving we get b=12cm and b=25 is neglected as b<l
l=25cm and b=12cm</span>
I think the answer is 19.5
Answer:
I believe there is something wrong with ur question.
The answer is 2.
The formula for slop is y2-y1/x2-x1
Using this formula we get 12-4/6-2 or 8/4 which simplifies to 2.
Hope this helps!
