Answer:
<h2>b = 41 mm</h2>
Step-by-step explanation:
From the question
Area of a triangle is given by
![A = \frac{1}{2} bh](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20bh)
where
b is the length of the base
h is the height
From the question
Area = 328 mm²
height = 16 mm
Substitute the values into the above formula and solve for the height
We have
![328 = \frac{1}{2} \times 16b \\ 328 = 8b](https://tex.z-dn.net/?f=328%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%2016b%20%5C%5C%20328%20%3D%208b)
Divide both sides by 8
We have the final answer as
<h3>b = 41 mm</h3>

Answer: 35%
Step-by-step explanation:
Given
Weight measured by Leo ![W_1=27\ pounds](https://tex.z-dn.net/?f=W_1%3D27%5C%20pounds)
Weight measured by the clerk ![W_2=20\ pounds](https://tex.z-dn.net/?f=W_2%3D20%5C%20pounds)
Percentage error is
![\Rightarrow \%\ \text{error}=\dfrac{\text{False value}-\text{Correct value}}{\text{Correct value}}\times 100](https://tex.z-dn.net/?f=%5CRightarrow%20%5C%25%5C%20%5Ctext%7Berror%7D%3D%5Cdfrac%7B%5Ctext%7BFalse%20value%7D-%5Ctext%7BCorrect%20value%7D%7D%7B%5Ctext%7BCorrect%20value%7D%7D%5Ctimes%20100)
Putting values
![\Rightarrow \%\ \text{error}=\dfrac{27-20}{20}\times 100=35\%](https://tex.z-dn.net/?f=%5CRightarrow%20%5C%25%5C%20%5Ctext%7Berror%7D%3D%5Cdfrac%7B27-20%7D%7B20%7D%5Ctimes%20100%3D35%5C%25)
