Answer:
1,164 in²
Step-by-step explanation:
the area of 1 sofa cushion = 
2× ( 10×11 + 10×4 + 11×4)
= 2 × (110+40+44)
= 2×(194)
= 388 in²
the fabrics she needs to cover 3 sofa cushions =
3 × 388 = 1,164 in²
 
        
             
        
        
        
The  airplane flies at 260 mi/h with no wind, while the rate of the wind is 60 mi/h.
<h3>What is an 
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let a represent the rate of the airplane with no wind. and b the rate of the wind, hence:
(a - b)3.2 = 640
a - b = 200   (1)
Also:
(a + b)2 = 640
a + b = 320    (2)
The solution to equation 1 and 2 is:
a = 260, b = 60
The  airplane flies at 260 mi/h with no wind, while the rate of the wind is 60 mi/h.
