The formula for the area of a trapezoid is a = one-half (b subscript 1 baseline + b subscript 2 baseline) times h when this equation is solved for b subscript 1, one equation is b subscript 1 baseline= startfraction 2 a over h endfraction minus b subscript 2. which of the following is an equivalent equation to find b subscript 1?

b₁ =   - b₂

This question is about change in subject of formula where one of the terms in the equation will be made the subject of the formula.

We are told that the area of a trapezoid is given as;

A= (b₁ + b₂)h

Now, we want to make b₁ the subject of the formula;

Let us multiply both sides by 2 to get;

2A = (b₁ + b₂)h

Let us now divide both sides by h to get;

= b₁ + b₂

Let us now subtract b₂ from both sides to get;

b₁ = - b₂
