if you're talking about a triangle then it's the bottom side well if you're talking about any shape it's the side the shape is supported on like if you put a box on the ground the face that is touching the ground is the base in this case it is the face that is supporting the rest of the shape
Let the smaller one is x so the larger is x+1 x(x+1)=1332 x^2+x=1332 x^2 +x -1332 =0 (x - 36)(x + 37) =0 so x = 36 or x = -37 therefor the larger integer is either 37 or -36
