: The figure above represents a square garden that is divided into 9
: rectangular regions with indicated dimensions in meters. The shaded regions
: are planted with peas, and the unshaded regions are planted with tomatoes.
: If the sum of the areas of the regions planted with peas is equal to the sum
: of the areas of the regions planted with tomatoes, what is the value of x?
: A. 0.5
: B. 1
: C. 1.5
: D. 2
: E. 2.5
: 答案給(c) 可是我卻一直算成(d)耶～
令中間那欄=9-3-X=6-x
因為下面兩列陰影跟非陰影的面積恰好相等
所以針對第一列來列式
3*x+3*3=(6-x)*3 ==>x=1.5
