The Cost of installing the artificial soccer pitch is $5360
A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are parallel and equal.
The soccer pitch us rectangle in shape. Hence:
Perimeter of soccer pitch = 2(length + width) = 2(91 + 43) = 268 meters
Cost of installing the pitch = $20 per meter * 268 meters = $5360
The Cost of installing the artificial soccer pitch is $5360

$480 is the price after the discount was added. We can then assume that $480 is 3/4 the price of the original item. To find 1/4, we simply divide by 3, which equals $160. since $160 is one quarter of the price, the original price was $640.
 
        
             
        
        
        
Depending on the values of  'r',  't', and  'e', the numerical value of that expression 
might have many factors.  
For example, if it happens that r=5, t=1, and e=4 for an instant, then, just 
for a moment,  (r + t)(e) = (5+1)(4) = 24, and the factors of (r+t)(e) are 
1,  2,  3,  4,  6,  8,  12, and  24 .   But that's only a temporary situation.
The only factors of (r+t)(e) that don't depend on the values of  'r',  't',  or  'e' ,
and are always good, are  (<em>r + t</em>)  and  (<em>e</em>) .
        
             
        
        
        
Well if her simplifies 1 3/7 to 1 1/2 and 5 4/5 to 6 then he would be overestimating because 1 1/2 is greater than 1 3/7 and 6 is greater than 5 4/5
Hope this helps!
