To find the equations that are equal to A = 1/2bh, we need to manipulate the original equation to solve for each of the other variables (b, h).
To solve for B:
A = 1/2bh
Multiply both sides by 2 to get rid of the fraction:
2A = bh
Now divide both sides by h:
B = (2A)/h
So, B = a/2h is equivalent to A = 1/2bh.
To solve for b:
A = 1/2bh
Multiply both sides by 2:
2A = bh
Now divide both sides by h:
b = (2A)/h
So, b = 2a/h is equivalent to A = 1/2bh.
To solve for H:
A = 1/2bh
Multiply both sides by 2:
2A = bh
Now divide both sides by b:
H = (2A)/b
So, H = 2a/b is equivalent to A = 1/2bh.
H(1/2) = a/b is not equivalent to A = 1/2bh.
In summary, equations 1, 2, and 3 are equal to A = 1/2bh.
