Question

4. If two perpendicular sides of a right
angled triangle are 6 cm and 8 cm, its
perimeter is​

Answer 1

Answer:

Step-by-step explanation:

wo sides are given, so we can find the third side of right angle ∆ by using Pythagoras theorem.

Pythagoras theorem states that, "In a right angled ∆, the sum of squares of two sides ( base and perpendicular ) is equal to the square to biggest side ( hypotenuse ).

(AC)² = (AB)² + (BC)²

(AC)² = 8² + 6²

(AC)² = 64 + 36

(AC)² = 100

AC = √100

AC = 10 cm

_______________________

★ Now perimeter of right angled ∆ = AB + BC + AC

=> 8 + 6 + 10

=> 24 cm

Hence, the perimeter of right angled ∆ is 24 cm.

I hope it will help you :-)
