Another problem 求助!
OG Problem Solving 16:
What is the combined area, in square inhes, of the front and back of a rectangular sheet of paper masuring 8 1/2 --
(17/2) by 11 inches?
A. 38
B. 44
C. 88
d. 176
e..187
What is "the combined area" here? 这道题看了半天都不懂 那个17/2 是长 or 宽 11inches是厚度吗
举报
就是一张长方形的纸正面的面积加上反面的面积一共多少?
即17/2*11*2=187
一个长方形,边长为17/2和11,求正面面积+反面面积
有厚度的是长方体,rectangular solid
楼主最好看下OG数学概念部分的review,对一些名词和定义熟悉一下
thanks a lot!!!!i will take the advice thank u=)
