Answer 1

Answer:

perimeter = PQ+QR+PR=12 3/4 cm

PQ=4 1/3cm

QR=5 1/4cm

PR=?

PR= perimeter-(PQ+QR)

={12 3/4-(4 1/3+5 1/4)} cm

={51/4-(13/3+21/4)}cm

={51/4-(13×4+21×3)/12} cm

={51/4-(52+63)/12} cm

={51/4-115/12} cm

={51×3-115}/12 cm

=(153-115)/12 cm

=38/12 cm

=19/6 cm

=3 1/6 cm

so , PR=3 1/6 cm
