Question

2. please explain your answer

Answer 1

The experimental value ( the height of the go wished frame) = 1.34 m

The true value. ( the supposed height) =1.25 m
The formula for percents error
$\frac{experimental \: value - true \: value}{true \: value} \times 100$

$\frac{1.34 - 1.25}{1.25} \times 100$
Subtract 1.34 by 1.25
$\frac{0.09}{1.25} \times 100$
Divide
$0.072 \times 100$
Multiply to convert 0.072 to percent

Percent error = 7.2%
