Answer:
10,10√2
Step-by-step explanation:
The breadth of the room (BD)=6m
The length of the room (CD)=8m
Therefore,
The length of the rod (BC)=?
According to pythagaras theoram
BC square=BD square +CD square
BC square =6 square +8 square
BC square =36+64
BC square =100
BC=√100=10
Again,
The legs are(CB)=10 and (x)=10 then the hypoteneous (y)=?
y square = x square + BC square
y square = 10 square +10 square
y square = 100+100
y square =200
y=√200=√10×10×2=10√2
