Answer:
b = 41 mm
Step-by-step explanation:
From the question
Area of a triangle is given by
[tex]A = \frac{1}{2} bh[/tex]
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
[tex]328 = \frac{1}{2} \times 16b \\ 328 = 8b[/tex]
Divide both sides by 8
We have the final answer as
b = 41 mm
