    Let x be equal to the area of Jasper, and y be equal to the area of Banff. We then have: x+y=17500 y-x=900 We can rearrange equation 2 to be y=900+x Substitute into equation 1 and we get x+900+x=17500 This becomes 2x=16600 So x=8300 km Then y=8300+900=9200 km So the area of Banff is 9200 km

    Oh shoot, didn't see the half. Allow me to fix that: x+y=17500 y-x/2=900 Proceed as in my initial reply, and you will eventually get: Something to the effect of 1.5x=16600 So area of Banff is approximately 6433.3 km... This is closer to the actual value according to Wikipedia.
