The formula for the area of a trapezoid is A = one-half (b Subscript 1 Baseline + b Subscript 2 Baseline) times h When this equa

sleet_krkn [62]

The equivalent equation is;

$\frac{2A}{h} -b_2=b_1$

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
