Answer 2

Solution:

It is said that a vertical pole casts a shadow of 4m where it's original height is 6m.

We are told to find the length of the tower who casts a shadow of 28 m long.

For this we are going to use the formula for Direct Proportion

$x_{1}$ / $y_{1}$ = $x_{2}$/ $y_{2}$

6 / 4 = $x_{2}$ / 28

6*28 = 4$x_{2}$

168 = 4$x_2$

168/4 = $x_2$

42 = $x_2$

Therefore, The height of the tower is 42m high.
