Question

How many rectangles are there in the following figure?

• A. $39$
• B. $25$
• C. $30$
• D. $38$

Answer 1

The correct option is A $39$

Total number of rectangles in figure $ABCD$. $3$ vertical lines and $5$ horizontal lines.
${}^5{C}_2{\times }^3{C}_2=30$
and $1,2,12,1F,2H,1FE,2HG,12FH,12EFGH$.
So, total $39$ rectangles.
