It can be seen that this is a big rectangle and a small rectangle, and each rectangle has two horizontal lines and four vertical lines.

Therefore, each rectangle is divided into small rectangles of different sizes, which * * * form-

(1+2+3) x (1+2+3+4+5) = 90 rectangles.

In addition, the four sides inside the rectangle are divided into six jumpers, resulting in

There are 2x6= 12 lines between two horizontal lines.

There are 2x4x( 1+2+3)=48 vertical lines.

So a * * * has 2x90+ 12+48=240.
