Answer:
Part 1 : 
Part 2 : 
w=6
l = 10 
Step-by-step explanation:
Part 1: 
Let the width of the rectangle = w
Length of the rectangle = w + 4
Area of the rectangle is given as 
60 Sq Yrds



Hence this expression represents the area of the rectangle. Solving which for w will give us the width of the rectangle. 
Part 2:
(w+10)(w-6)= 0 
either (w+10) = 0 
or 
(w-6)=0 
or both are zero 
(w+10) = 0 ⇒ w = -10
not possible as the dimension can not be 0
(w-6)=0  ⇒ w=6 
Hence the width is 6 yards
And thus the length will be 6+4 = 10 yards
 
        
             
        
        
        
894 mi^2
as 24 x 37.25 = 894
        
             
        
        
        
Answer:
28.26m^2 (aka. 28.26 meters squared)
Step-by-step explanation:
The area of a circle is A=pi*r^2 where r is the radius of the circle.
Since r=3, then A=pi*3^2=9pi=28.26
Therefore, the area of the merry-go-round is 28.26 square meters
 
        
             
        
        
        
148.57-94 would equal 54.57
