The formula \(A = bh\) needs to be rearranged to make \(b\) the subject of the formula. \(A = bh\) means \(A = b \times h\). To make \(b\) the subject of the formula, \(b\) needs to be isolated.

For each step make sure that the inverse is applied to both sides of the formula. When the new subject is isolated, the rearranging process is complete. A formula is rearranged by using inverse ...
