**Steve**, Sunday, February 19, 2012 at 9:12pmcenter the door way so that half the base is 3+x feet. The area of the triangle is 98, so the height h = 98/(3+x)

using similar triangles,

8/x = h/(x+3)

8(x+3) = hx

8(x+3) = 98/(x+3) * x

4x^2 - 25x + 36 = 0

(4x-9)(x-4) = 0

Looks like any x from 9/4 to 4 will work. So, the dimensions can vary from

10.5 ft wide x 18 2/3 ft high

to

14 wide x 16 ft high
