The answer is 20%.
Step 1: Subtract the measured distance and the actual distance to calculate the error.
Step 2: Divide the given value by the actual distance and convert it into the percentage.
the actual distance is 612 ft
the measured distance is 735 ft
Step 1: 735 ft - 612 ft = 123 ft
Step 2: 123 ft / 612 ft = 0.20 = 20/100 = 20%
        
                    
             
        
        
        
3a + 6b = 45
2a - 2b = -12....multiply by 3
----------------
3a + 6b = 45
6a - 6b = - 36 ...(result of multiplying by 3)
---------------add
9a = 9
a = 1
3a + 6b = 45
3(1) + 6b = 45
3 + 6b = 45
6b = 45 - 3
6b = 42
b = 7
solution is : (1,7)
