ΔPQR is similar to ΔUVW. Perimeter of ΔPQR and ΔUVW are 120 cm and 240 cm respectively. If PQ = 30 cm, then what is the length of UV?
Answer & explanation
Correct answer: option 2
Using the concept
= (perimeter of \(\Delta \)PQR)/(perimeter of \(\Delta \)UVW) = \(\frac{PQ}{UV}\)
= \(\frac{120}{240}\) = \(\frac{30}{UV}\)
= \(\frac{1}{2}\) = \(\frac{30}{UV}\)
= UV = 60
Therefore UV is 60.
