A=½(a+ b) h ,express a interns of a, b and h

Answer 1

To express a in terms of a, b, and h, we can isolate a in the formula:

A = ½(a + b)h

First, multiply both sides by 2 to eliminate the fraction:

2A = (a + b)h

Next, distribute the h:

2A = ah + bh

Now, isolate the term with 'a' on one side:

2A - bh = ah

Finally, divide both sides by h to solve for a:

a = (2A - bh) / h

Therefore, a can be expressed in terms of a, b, and h as:

a = (2A - bh) / h.
