Question

pqrs is a square and qtr is a triangle whose two angles viz <tqr and<trq are each 60°.lf qt =rt =7cm ,find the perimeter of pqrs.​

Answer 1

Answer:

qt=rt =7cm

angle tqr=angle trq=60°

so angle qtr is also 60°

so ∆qtr is a equilateral triangle,each side is 7cm.

so qr is 7 cm

so the peri meter of the square pqrs is

7×4cm=28cm
