Answer:
(a) Let the length of the shadow be x m.
5 m 60 cm = 5.60 m Height 5 m 60 cm 10 m 50 cm Length 3 m 20 cm x 3 m 20 cm = 3.20 m 10 m 50 cm = 10.50 m \[\therefore \] \[\frac{5.60}{3.20}=\frac{10.50}{x}\] \[\Rightarrow \] \[x=\frac{10.50\times 3.20}{5.60}\] \[\Rightarrow \] x = 6m (b) Let the height of a pole be y m.
\[\frac{5.60}{3.20}=\frac{y}{5}\] Height (m) 5.60 cm y Length (m) 3.20 cm 5 \[\Rightarrow \,\,\,y=\frac{5.60\times 5}{3.20}=8.75\] or y = 8 m 75 cm
