最佳解答:
1. The width of the rectangle =72/2-19cm =36-19cm =17(cm) 2. The differemce of the temperature =34-25'C =9'C The percentage increase =9/25*100% =36%
其他解答:
1. Let w cm be the width of the rectangle 2 * (19 + w) = 72 w + 19 = 36 w = 17 The width of the rectangle is 17cm 2. Percentage change = (34 - 25) / 25 * 100% = 9/25 * 100% =36% The percentage increase in temperature is 36% 3. Profit percentage = (2-1)/1 * 100% = 100%
