a community swimming pool is in the shape of a trapezoid. The height is the trapezoid is twice as long as the shorter base and longer base is twice as long as the height (length is 4, width is 2)
The area of the pool is 3675 square feet. what is the length of the longer base?
(A=1/2h(b1+b2).) I don't understand please help

First you need to visualize the pool|dw:1427645226346:dw|
This is how it would look (not drawn to scale).  
@flirty45 do understand the drawing, the Area formula is from your text or Google search.

radar · Answer

After getting an understanding, you need to take the information provided by the problem and determine an equation that relates what you have been given for the area to the dimensions of the pool.

radar · Answer

I am suggesting relate all the dimensions (b1, b2 and h) to b1.

Will continue when you are back.

where the h is should be 2x and b2 is 4x

radar · Answer

This info is provided:
b1 = b1
h=2b1
b2=4b1  this is because 2h = 4b1
Now you have enough to write an equation for area (3675)
