Question

given:ray LMN//NP set LN// ray PQ if m <MKN =100° and m <KLM =45° find x, y,a ​

Answer 1

Answer:

LM=9cm

MN=12cm

LN=15cm

∴PM=4.5cm

QN=7.5cm

And we know that the line joining the mid points of the two sides of a triangle is parallel to the third side and is equal to half of it.

∴PQ=

MN=6cm

(i)Perimeter of trapezium MNQP=(4.5+7.5+12+6)

=24+6

=30cm

(ii)Area of trapezium=

×(12+6)×4.5

=9×4.5

=40.5cm
