Answer 1

60.1 mm

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

Answer 2

Height (h) =54.6mm

Explanation:

Given :

Base (b) = 7.7mm

Area (a) = 210.21mm^2

Height (h) = ?

`Area = (base* height)/(2) \\\\210.21= (7.7* h)/(2) \\\\210.21*2 = 7.7* h\\\\420.42 = 7.7 h\\\\(420.42)/(7.7)=(7.7h)/(7.7)\\\\54.6 =h\\\\h=54.6`
