Answer (3)
A = 1/2 b h
Multiply each side by 2 : 2A = b h
Divide each side by ' h ' : *** 2A/h = b***
When solving the **formula **A = (1/2)bh for b, the **value **of b is given by b = 2A / h.
What is 'b' as the subject of the formula in the equation?
Given the **equation **in the question:
A = 1/2 × bh
To solve the formula A = (1/2)bh for b, we need to isolate the **variable **b.
A = 1/2 × bh
To isolate b, we need to get rid of the term that is multiplied by b, which is (1/2).
The opposite operation of multiplication is division, so we will multiply both sides of the equation by 2:
2 × A = 2 × 1/2 × bh
2A = 2/2 × bh
2A = bh
bh = 2A
Now, to solve for b, divide both sides of the equation by h:
bh/h = 2A/h
b = 2A/h
Therefore, the variable b equals 2A/h.
