Question

The area of a trapezoid is given by the formula A=1/2h(B+b). solved for b, this formula becomes b=

Answer 1

`A=(1)/(2)h(B+b)` Solve for b (isolate/get b by itself):

`A=(1)/(2)h(B+b)` Multiply 2 on both sides to get rid of the 1/2

`2A=h(B+b)` Divide h on both sides

`(2A)/(h) =B+b` Subtract B on both sides

`(2A)/(h)-B=b`
