The height of the shadow from the meter ruler is 50cm. Determine the height of the house if the length of the shadow from it is 1m50cm.
To find out the height of the house, we will use the ratio: Ld / Ll = Nd / Nl, from where we express: Nd = Nl * Ld / Ll.
Data: Hl – the height of the taken ruler (Hl = 1 m); Ld – the length of the shadow from the house (Ld = 1 m 50 cm, in the SI system Ld = 1.5 m); Ll – the length of the shadow from the ruler (Ll = 50 cm, in the SI system Ll = 0.5 m).
Let’s perform the calculation: Nd = Nl * Ld / Ll = 1 * 1.5 / 0.5 = 3 m.
Answer: The house, according to the calculation, has a height of 3 meters.
