Answer:
15cm
Step-by-step explanation:
Perimeter of Δ ABC = sum of all sides
= AB + BC + CA
= 5 + 13 + 12
= 30 cm
Now, let α be side of square-
(square & triangle's perimeter is same)
.:. Perimeter od Square PQRS = sum of all side
30 = α+α+α+α
30 = 4α
30/4 = α
7.5 = α
(perimeter us twice so,)
Therefore side of square = 2 x 7.5 cm
= 15cm
