b, base
h, altitude
b-h=4

Area is calculated just like a rectangle.

b%2Ah=71
%284-h%29h=71
4h-h%5E2-71=0
highlight%28h=%281%2B-+sqrt%281-4%2A4%28-71%29%29%29%2F%282%2A4%29%29 and you want the PLUS square root form.

h=%281%2Bsqrt%281137%29%29%2F8

Altitude: highlight_green%286.660254038%29
Base: 6.660254038 + 4, or highlight_green%2810.660254038%29
