Question

in triangle ABC, P is midpoint of AB and Q is midpoint of AC. If AB =9.6cm BC=12cm and AC =11.2cm find the perimeter of the trapezium.​

Answer 1

Answer:

26.9 cm

Step-by-step explanation:

As P is the midpoint of AB,

∴PB=(1/2)(AB)=9.6/2=4.8cm

As Q is the midpoint of AC,

∴CQ=(1/2)(AC)=11.2/2=5.6cm

Also, PQ will be parallel to BC from the midpoint theorem.

∴PQ=(1/2)(BC)=11/2=5.5cm

∴ Parimeter of trapezium

=PB+BC+CQ+PQ

=4.8+5.6+5.5+11

=26.9cm
