Hope this helps you and comment if you need an explantion
The area of a trapezoid is
A = (1/2) (h) (b1 + b2).
( 'h' is the height of the trapezoid. 'b1' and 'b2' are its two bases.)
You want the equation solved for one base.
A = (1/2) (h) (b1 + b2).
Multiply each side by 2 : 2A = h(b1 + b2)
Divide each side by 'h' : 2A/h = b1 + b2
Subtract b1 from each side: <em>2A/h - b1 = b2</em>

1.000000001 i think
Step-by-step explanation:
The best method would be to cross-multiply. Multiply the figure on the top left with the bottom right. Then set it equal to the multiplication of the bottom left with the top right.
This would turn into:
-1(x-1)=2(x+3) Then distribute the multiplication through the parentheses.
-x+1=2x+6 Next, get all the variables on one side, and the integers on another.
2x+x=1-6
3x= -5
x= -5/3
