Answer:
Given - two perpendicular side of a right angle triangle are 5 cm and 12 cm
To Find :- Perimeter = ?
Solution :
Let us assume that, hypotenuse of the right angled A is x cm.
so, using pythagoras theorem we get, → x² = 5² + 12²
→x² = 25 +144
→ x² = 169
→ x² = (13) ²
→ x = 13 cm.
then,
→ perimeter of A = Sum of all sides
→ Required perimeter = 5 + 12 +13
→ Required perimeter = 30 cm (Ans.D)
Hence, perimeter of given right angled
triangle is 30 cm.
