Hi ac lim, for B why is it 23x5 and not 23x10?

Total have 2B.
If you calculate 1B is ½ × 23 × 5 than ×2 =115
If you calculate 2B is ½ × 23 × 10 =115

It depend on your calculation. Total 2B should be 115.

Hope this helps

Sorry.. but the triangle length is 10cm.
How come the shaded length becomes 5cm instead of 10cm?
