Metres long.
To find the length of the shadow cast by the flagstaff at a certain time of day, we need to use the concept of similar triangles.
Let's call the length of the shadow x. Then, we have the following proportion:
height of flagstaff / length of shadow = height of object casting the shadow / length of object's shadow
Substituting the values we know, we get:
6 / 2 = h / x
Simplifying, we get:
3 = h / x
To solve for x, we can multiply both sides by x:
3x = h
Substituting the height of the flagstaff, we get:
3x = 6
Dividing both sides by 3, we get:
x = 2
Therefore, the length of the shadow cast by the flagstaff at this particular time of day is 2 metres.
