Question

the perimeter of square pqrs into the perimeter of triangle ABC find the area of a square​

Answer 1

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
