Answer:
4.3362962963
Explanation:
A=1/2bh
29.7cm^2=1/2 13.5h
You're gonna multiply each side by 2 to cancel out the fraction equaling,
58.54= 13.5h
You're then gonna divide w=each side by 13.5 to get h left alone on one side and a number on the other equaling your answer. 4.3362962963. Round to whatever decimal place you need.
