[xoxo_lucinda]

Okay the question is: The area of a trapezoid is 80ft. It's bases have lengths 26ft and 14ft. Find it's height.

I really need help, if u can help me I would really appreciate it as soon as possible, Thank You :!:

Area of trapezoid = (a+b)/2 * h

Where a and b are the lengths of the two bases, and h is the trapezoid's height.

Substitute in what you know and solve for h.

(The area should be 80 ft^2, by the way.)
