The simplest rectangles are AEHG, EFJH, FBKJ, JKCL and GILD i.e 5 in number.
The rectangles composed of two components each are AFJG and FBCL i.e 2 in number
Only one rectangle namely AFLD is composed of three components and only one rectangle namely ABCD is composed of five components.
Thus, there are 5 + 2 + 1 + 1 = 9 rectangles in the given figure.
