The lengths of the sg zzou0x7 o6f (fvg7ds3/yd s5)1g7li:mied0tq:r rcides of a rectangular plate are measured, and the diagram shows the measured values with their uncertaintieqim:)ce7 i grt r0:1lds.

What is the percentage error in the area of the plate?   %. (Remember to exclude the % symbol with your answer.)




参考答案: 6


本题详细解析:
Area involves a multiplication so the percentage uncertainties need to be added.d2ugrp+ekn rlp(y37, Uncertainty in length is one part in 50, i.e. 2%; and in the height it is one part in 25 or 4%. Adding the uncertainti23 ulnygdp +er( ,rp7kes gives 6%.
