Answer:

Hey mate!!!

your answer:

Let AC = x

By Pythagoras theorem

x =  \sqrt{ {13}^{2} -  {12}^{2}  }

x =  \sqrt{169 - 144}

x =  \sqrt{25}  = 5

Perimeter

13 + 5 + 12 = 30

Area

 \frac{1}{2}  \times 12 \times 5

 6 \times 5

30

please Mark as brainliest ❤️

Step-by-step explanation:

(Ac)² = 13² - 12² ( Pythagoras theorem)

AC² = 169 - 144

AC² = 25

AC = 5 cm.

Perimeter of a triangle = sum of all sides.

= 5 + 13 + 12 = 30 cm.

Area of a triangle = 1/2bh

1/2 × 12 × 5

= 30cm².
