A) 15m
B) 32m
C) 16m
D) 8m
Correct Answer: D
Solution :
Given, AC = 40 cm Let length of the shadow of Vijay's house be AB = l m Since, \[\Delta ABE\tilde{\ }ACD\] \[\therefore \,\,\,\,\,\,\,\frac{AB}{AC}=\frac{EB}{CD}\] \[\Rightarrow \,\,\,\,\,\,\,\,\,\frac{l}{40}=\frac{20}{100}\] \[\Rightarrow \,\,\,h=\frac{20\times 40}{100}=8\,m\]You need to login to perform this action.
