$${\mathtt{A}} = \left({\frac{{\mathtt{b1}}}{{\mathtt{2}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{b2}}}{{\mathtt{2}}}}\right){\mathtt{\,\times\,}}{\mathtt{h}}$$ the b1 are down and b1+b2 divde by 2, What are ALL the variations
what is the formula for b1?
+4473 A = (b1/2 + b2/2)h
1) A/h = b1/2 + b2/2 --> A/h - b2/2 = b1/2 --> 2A/h - 2b2/2 = b1 --> b1 = 2A/h - (b2).
2) A/h = b1/2 + b2/2 --> A/h - b1/2 = b2/2 --> 2A/h -2b1/2 = b2 --> b2 = 2A/h - (b1).
3) 2A = (b1 + b2)h --> 2A/(b1+b2) = h.
+4473 A = (b1/2 + b2/2)h
1) A/h = b1/2 + b2/2 --> A/h - b2/2 = b1/2 --> 2A/h - 2b2/2 = b1 --> b1 = 2A/h - (b2).
2) A/h = b1/2 + b2/2 --> A/h - b1/2 = b2/2 --> 2A/h -2b1/2 = b2 --> b2 = 2A/h - (b1).
3) 2A = (b1 + b2)h --> 2A/(b1+b2) = h.
