Question

A building 25 metre high cast a shadow of 3.125 m .What could be the height of a pole which cast a shadow of 1.2 metre at the same time ?​

Answer 1

Answer:

Its a simple rule of three

Step-by-step explanation:

we will start out by finding how much 1 meter of shadow is by using the rule of three.

25     3.125

x         1                  x=height of object that casts the shadow

25 times 1=3.125 times x

25=3.125x

x=25/3.125

x=8

so if for every 1 metre of shadow, we have 8 metres of height that means that:

1.2 times 8=9.6 metres of height

to conclude the height of the pole is 9.6 metres
