Question

Zac wants to have a flower bed in his backyard. He measures the area of the flower bed to be 70 square feet. The actual measurement of the flower bed is 80 square feet. What is Zac's percent error in his measurement of the flower bed's area?

Answer 1

Zac's percent error in his measurement of the flower bed's area is 12.5%.

Step-by-step explanation:

Zac wants to calculate the percent error in his measurement of the flower bed's area. To find the percent error, we use this formula:

• Percent error = (|True value - Measured value| / True value) × 100%

The true value of the flower bed's area is 80 square feet, and Zac measured it as 70 square feet. Plugging these values into the formula gives us:

• Percent error = (|80 - 70| / 80) × 100%
• Percent error = (10 / 80) × 100%
• Percent error = 0.125 × 100%
• Percent error = 12.5%

Therefore, Zac's percent error in his measurement is 12.5%.
