The equation of a triangle would be : (base x height)/2 

Please specify what you mean by equivalent formula as this the the best and easiest one to use 

I have noticed that :

vest = 4 letters = 20 dollars

socks = 5 letters = 25 dollars 

tie = 3 letters = 15 dollars 

blouse = 6 letters = 30 dollars 

MEANING: each letter is 5 dollars 

underwear = 9 letters = 9 x 5 = 45 

Hope this helps !

No solution I might be wrong  can someone confirm?

Half circle : r = 3 thus 1/2 x pi r ^ 2 = 14.135

4 x 5 = 20 

2 x 6 = 12 

4 x 7 = 28 

Thus the answer would be : 14.135 + 20 + 12 + 28 = 74.135

Break these questions into multiple basic shapes and then solve 

I think it would be -12, use the infinite geometric series equation :

For this equation, it would be: x / ( 1 - 0.5x^2)

set this equation to equal -12, you will get 2 different x answers x = -4/3 and x = 3/2, however, one is eliminated 

x = - 1 (1/3 )
