Answer 1

Answer:

Given- perimeter of ∆ABC = perimeter of ∆PQR

Step-by-step explanation:

So. Perimeter of a triangle = sum of all three sides

perimeter of ∆PQR = PQ+QR+RP

=6cm+10cm+14cm =30cm

So Perimeter of ∆ABC =30cm

In ∆ABC. AB+BC+CA=30cm

13cm+5cm+AB=30cm

AB=30-18cm

AB=12cm

Area of triangle =1/2×b×h

=1/2×5cm×12cm

=30cm^2
