Answer:

Height (h) =54.6mm

Step-by-step explanation:

Given :

Base (b) = 7.7mm

Area (a) = 210.21mm^2

Height (h) = ?

[tex]Area = \frac{base\times height}{2} \\\\210.21= \frac{7.7\times h}{2} \\\\210.21\times2 = 7.7\times h\\\\420.42 = 7.7 h\\\\\frac{420.42}{7.7}=\frac{7.7h}{7.7}\\\\54.6 =h\\\\h=54.6[/tex]

Answer:

60.1 mm

Step-by-step explanation:

The formula for the area of a triangle of base b and height h is A = (1/2)(b)(h).

We are to find the height of the given triangle, so solve this last equation for h:

2A = (b)(h), or h = 2A/b

Substituting 210.21 mm^2 for A and 7.7 mm for b, we get:

       2(210.212 mm^2)

h = --------------------------- = 60.1 mm

               7 mm
