MnO4−(aq) + SO32−(aq) + H+(aq) → Mn2+(aq) + SO42−(aq) + H2O(l) in the form a*MnO4−(aq) + b*SO32−(aq) + c*H+(aq) → d*Mn2+(aq) + e*SO42−(aq) + f*H2O(l) Start by counting how many of each are on each side. I'm going to choose to...

How many squares are on each side? x*y = 49 where x the number of squares for the width, and y is the number of squares for the length. 120000 = X*Y where X is the width in feet, Y is the length in feet 120000/49 = (X/x) * (Y/y) You have X/x = Y/y
