Question

Find the height of the figure below if the triangle is an equilateral triangle and the surface area is 51.678 mm^2

Answer 1

SA=bh

The base is an equilateral triangle that means that the base=2.7^3=19.683

51.678=19.683h

divide both sides by the base

`(51.678=19.683h)/(19.683)`

2.626mm=h
