InterviewSolution

1.	`Delta ABC~ DeltaDEF` such that `ar (Delta ABC)= 36 cm^(2) and ar (Delta DEF) 49 cm^(2)` . Then, the ratio of their corresponding sides isA. `36:49`B. `6:7`C. `7:6`D. `sqrt(6):sqrt(7)`
Answer» Correct Answer - B `((AB)/(DE))^(2)=(ar(Delta ABC))/(ar (Delta DEF))=(36)/(49)=((6)/(7))^(2) rArr (AB)/(DE)=(6)/(7)` `:.` the ratio of the corresponding sides is `6:7`
