Yes, it is true.
________________
For example,
take two integers 12 and 4
12 × 4 = 48 : product is positive
12 ÷ 4 = 3: quotient is positive
____________________
If you take -12 and 4
-12 × 4 = -48 : product is negative
-12 ÷ 4 = -3: quotient is negative
        
             
        
        
        
Answer with explanation:
Class Interval             Variate         Frequency
 16-18                              16                     1
 19-21                               0                     0
 22-24                               0                    0
 25-27                              26,27              2
 
        
             
        
        
        
Width of rectangle = x
Length =3x+7
Perimeter of rectangle = 158cm
2(l+w)=158
2(3x+7+x)=158
2(4x+7)=158
8x+14=158
8x=158-14
x=144/8
x=18
Therefore the width of the rectangle is 18cm
Length=3x+18+7
54+7=61cm
Area=lxw 
=61x18
=1098^2
