Answer 2

The height of the bottom of the bulb from the floor is 2 m 40 cm

Step-by-step explanation:

The height of a room is 3 m 50 cm or 350 cm

Because 1 m = 100 cm

The length of wire is 1 m or 100 cm

The size of bulb is 10 cm

Please find the attachment for figure.

Let the height of bottom of bulb is h from floor.

Sum of of height of bulb from floor , size of bulb and length of wire is equal to height of room.

Therefore,

h + 10 + 100 = 350

                 h = 350 - 10 -100

                h = 240 cm

Now convert cm to m

So, 240 cm =  2 m 40 cm

Hence, the height of the bottom of the bulb from the floor is 2 m 40 cm
