Hannah wanted to find the area of a square.

She measured the length of the square as 3.5 cm.
Later, the actual length of the square was more accurately measured as 3.4 cm.

What is the relative error in her area calculation to the nearest hundredth?

Respuesta :

Answer: 2.86%

Step-by-step explanation:

The formula for relative error is given by:

Relative error = (Measured value - Real value)/Real value × 100

Relative error = [(3.4 - 3.5)/3.5] × 100

= -1/3.5 × 100

= 1/35 × 100

= 2.86%
