Answer: 659 13/18 yd^2 or 659.7yd^2                ^ =squared
Step-by-step explanation:
This is the answer because you have 6 sides of this prism. That means 3 sides are parallel to the sides across from them. So, 12 1/2 yd by 8 1/3 yd is 104 1/6, then multiply by 2. That equals 208 1/3. Then, 10 5/6 yd by 8 1/3 yd is 90 5/18. then times by 2. That equals 180 5/9. Next, 10 5/6yd by 12 1/2 is 135 and 5/12. then times by 2 and that is 270 5/6yd.
add 208 1/3 + 180 5/9 + 270 5/6
659 13/18 yd^2
 
        
             
        
        
        
Answer:
1) $16.35
2) 75%
3) $245  
Step-by-step explanation:
1) Jada earns = $15 per hour
   9% increase = 15 * 9/100 = $1.35 
   Increased Jada's pay = 15+1.35 = $16.35
2) Markup = selling price - cost= $350 - 200= $150
    Markup % =  \
 \
                       =  = 75%
 = 75%
3) Jada's sister commission is 3.5% of $7000
           = 
            = $245
