Let 

 be the length of the rectangle and 

 be the width. In the problem it is given that 

. It is also given that the area 

. Substituting in the length in terms of width, we have 

. Using the zero product property, 

. Solving these we get the width 

. However, it doesn't make sense for the width to be negative, so the width must be 

. From that we can tell the length 

. 
 
        
        
        
Answer:
D
Step-by-step explanation:
 
        
             
        
        
        
The diagonals of a rhombus are perpendicular bisectors of each other, and are also angle bisectors. The 4 congruent right triangles the rhombus is cut into by the two diagonals are 30-60-90 degree triangles, the longer leg is √3/2 of the hypotenuse, √3/2 of 10=5√3. so the longer diagonal is twice of 5√3=10√3 
        
             
        
        
        
Answer:
 1.5225 gumbo squared
Step-by-step explanation:
First we know that 1 gumbo is equal to 8.5 lollygams.
To know the number of gumbo squared in 110 lollygam squared, we need to know the relation between 1 gumbo squared and 1 lollygam squared, and we do that making the square of our relation between gumbo and lollygams:
1 gumbo -> 8.5 lollygams
1 gumbo squared -> (8.5)^2 lollygams squared = 72.25 lollygams squared
Now, to know the number of gumbo squared in 110 lollygam squared, we just need to divide 110 by 72.25:
1 gumbo squared -> 72.25 lollygams squared
x gumbo squared -> 110 lollygams squared
x = 110/72.25 =  1.5225 gumbo squared
