A = BH/2   --- Equation for triangle area
54.52cm² = B(11.6cm)/2   --- Substitute the numbers in for Area and Height
   2                     2   --- Multiply both sides by 2
_______________
109.04cm² = (11.6cm)B   
/11.6cm            /11.6 cm   --- Divide both sides by 11.6cm to isolate B
_________________
9.4cm = B    ---Length is equal to 9.4 cm.
