Answer:
The choice three;
[tex]b = \frac{2A}{h} [/tex]
Step-by-step explanation:
[tex] \frac{1}{2} bh = A \\ b = A \div ( \frac{1}{2} h) \\ b = A \times ( \frac{2}{h} ) \\ \\ b = \frac{2A}{h} [/tex]
I think the answer is the third
thirdone
1/2 bh = A
bh = 2A (1/2 move to the other side and multiply 2 by A)
b = 2A/h (h move to the other side and divide 2A by h)
Hope you can understand ittttt^^
