3.1f AXYZ ~ APQR and A(AXYZ) = 25 cm2 ,A(APQR) = 4 cm2 then XY: PQ =?
(A) 4:25
(B)2:5
(C) 5:2
(D)25:4
Answers
Answer:
(C)5:2
Step-by-step explanation:
Given,
Given, ∆XYZ ~ ∆PQR(Similar)
Area of ∆ XYZ = 25 cm²
Area of ∆ XYZ = 25 cm²Area of ∆ PQR = 4 cm²
Area of ∆ XYZ = 25 cm²Area of ∆ PQR = 4 cm²We know that ,
Area of ∆ XYZ XY²
Area of ∆ XYZ XY²--------------------- = --------
Area of ∆ XYZ XY²--------------------- = -------- Area of ∆ PQR PQ²
Therefore, XY √25 5
Therefore, XY √25 5 ----- = ------- = ---- = 5:2
Therefore, XY √25 5 ----- = ------- = ---- = 5:2 PQ √4 2
Therefore, XY √25 5 ----- = ------- = ---- = 5:2 PQ √4 2XY:PQ = 5:2
