The formula to calculate the area of a triangle is

[tex]A=\frac{p\cdot b}{2}[/tex]

in our case we have p is the height of the triangle, and b is the base of the triangle

A=184 mm^2

b=16mm

we substitute the data given

[tex]184=\frac{p\cdot16}{2}[/tex]

then we isolate the p

[tex]p=\frac{184\cdot2}{16}[/tex][tex]p=23[/tex]
