Question

Solve the word problem.  The height of a triangle with base b and area A is given by the formula h = 2A/B .  What is the height of a triangle with area 26 cm2 and base 8 cm?  
A.1.625 cm  
B.3.25 cm  
C.3.5 cm  
D.6.5 cm

Answer 1

$h = \frac{2A}{b} \ \ \ and\ \ \ A=26\ cm^2\ \ \ and\ \ \ b=8\ cm\\\\h= \frac{2\cdot26}{8} = \frac{2\cdot2\cdot13}{2\cdot2\cdot2} = \frac{13}{2} =6.5\ [cm]\\\\Ans.\ D$
