Sagot :
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
