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
