Reflect over
This means that we reflect over the x-axis
And the rule of reflection is:
Hence:
Will become:
So, we have:
The equivalent equation is;
Step-by-step explanation:
Given that the area of a trapezoid is ;
A=1/2 (b₁+b₂)h
When the equation is solved for b₁ it will be;
A=1/2 (b₁+b₂)h
This can be written as;
A=h/2 (b₁+b₂)
Multiply both sides by 2/h
2A/h = b₁+b₂
Make b₁ subject of the formula
2A/h - b₂ = b₁
