This answer was edited.Given, Two poles of heights 6 m and 11 m stand on a plane ground.

And distance between the feet of the poles is 12 m.

Let AB and CD be the poles of height 6m and 11m.

Therefore, CP = 11 â€“ 6 = 5m

From the figure, it can be observed that AP = 12m

By Pythagoras theorem for Î”APC, we get,

AC

^{2}=AP^{2}+ PC^{2}(12m)

^{2}Â + (5m)^{2}Â = (AC)^{2}AC

^{2}Â = (144+25) m= 169 mAC = 13m

Therefore, the distance between their tops is 13 m.

## Two poles of heights 6 m and 11 m stand on a plane ground. If the distance between the feet of the poles is 12 m, find the distance between their tops. Q.12
