The length of Dwight's garden is 12.5 meters. Dwight measured it but made a measurement error of 6%. Find the lowest and highest

pishuonlain [190]

Answer: See Explanation

Step-by-step explanation:

From the question, The length of Dwight's garden is 12.5 meters but he measured it and made a measurement error of 6%.

The lowest measurement Dwight could have made will be:

= 12.5 - (6% × 12.5)

= 12.5 - (0.06 × 12.5)

= 12.5 - 0.75

= 11.75 meters

The lowest measurement Dwight could have made will be:

= 12.5 + (6% × 12.5)

= 12.5 + (0.06 × 12.5)

= 12.5 + 0.75

= 13.25 meters
