Answer:
![b=\dfrac{2A}{h}](https://tex.z-dn.net/?f=b%3D%5Cdfrac%7B2A%7D%7Bh%7D)
Step-by-step explanation:
The formula for the area of a triangle is given by :
...(1)
Where b is the length of the base and h is the height.
We need to find the value of b from the above formula.
Cross multiplying equation (1) we get :
![2A=bh](https://tex.z-dn.net/?f=2A%3Dbh)
Now dividing both sides by h. So,
![\dfrac{2A}{h}=\dfrac{bh}{h}\\\\b=\dfrac{2A}{h}](https://tex.z-dn.net/?f=%5Cdfrac%7B2A%7D%7Bh%7D%3D%5Cdfrac%7Bbh%7D%7Bh%7D%5C%5C%5C%5Cb%3D%5Cdfrac%7B2A%7D%7Bh%7D)
So, the correct option is (D) i.e.
