Question

Find the height of a pole that cast a shadow of length 5 metres at a time and place where the shadow of a stick 5 cm long is 2 metres

Answer 1

ANSWER = 12.5 cm

length of stick = 5cm

length of shadow = 2m

ratio of stick to shadow = 5 / 200

= 1 / 40

the ratio of shadow to figure is constant

length of shadow of pole = 5 m = 500 cm

length of pole = x

x / 500 = 1/ 40

x = 500 / 40

x = 12.5 cm
