Question

For ∆XYZ ~∆MNP the perimeter of ∆XYZ is 8.4, if YZ =2NP then the perimeter of ∆MNP is

Answer 1

∆XYZ~∆MNP

So,

XY/MN = YZ=NP = XZ=MP. (C.P.S.T.)

Perimeter of∆XYZ/Perimeter of∆MNP = YZ=NP

8.5/ Perimeter of ∆ MNP = 2NP/NP (YZ = 2NP)

8.4 / Perimeter of ∆ MNP = 2

Perimeterof ∆MNP = 2/8.4

= 20/84 units.
