Question

A=½(b+c)h solve for c​

Answer 1

a=(1/2(b+c))(h)

1/2bh+1/2ch=a

1/2bh+1/2ch+−1/2bh=a+−1/2bh

1/2ch=−1/2bh+a

1/2chh/2=−1/2bh+ah/2

c=−bh+2a / h

Answer 2

Hi there!

Your answer is:

c= -b + (2A)/H

First: Multiply both sides by 2

A= 1/2 (b+c)h

× 2

2A = (b+c)h

Next, divide both sides by h

2A/H = b+c

Finally, subtract b

2A/H -b = c

Hope this helps
