A long horizontal piece of wood EF is suspended above the ground, as shown in the diagram, by two ropes EB and FD which are tied to two bamboo
poles AB and CD of equal lengths. The bamboo poles are at equal distances from the edge of wooden piece. The bamboo poles are supported by two
different ropes GB and HD respectively as shown in the figure. Choose the correct options

Answer:
it's 3
Step-by-step explanation:
its 3 because Total length of the height of the pole are 4 ft and G and B is 3 ft because 1 ft is shorter than pole so that's why D and H is also same .
hope it helps
