Answer:
Step-by-step explanation:
√14 cannot be rewritten as the ratio of two integers and thus is irrational.
Similarly, √99 is irrational; √99 = √9√11 is irrational even though √9 is not.
 
        
             
        
        
        
Length(l)= 2w
width(w)= w
Perimeter(P)= 2w+2l= 72 (simplify expression: divide each side by 2 )
P= w+l= 36 (plug in "2w" for "l")
P= w+(2w)= 36
P= 3w= 36 (divide each side by 3 to find the width)
w= 12 units
find length:
l=2w
l= 2(12) 
l= 24 units
Answer:
The length of this rectangle is 24 units and the width is 12 units.
