Question

- If the two perpendicular sides of right angle
triangle are 5 cm and 12 cm, then the
perimeter of triangle is
(a) 13 cm
(b) 17 cm
(c) 27 cm
(d) 30 cm
​

Answer 1

Answer:

(d) 30cm of the perimeter of triangle

Answer 2

Answer: 30

Step-by-step explanation:

p²+b²=h²

P is perpendicular

B is base

H is hypotenuse

Given two sides are perpendicular and base because they're at right angle to each other.

So, 5²+12²=square of third side (hypotenuse)

So third side is √(25+144)

Or √169=13

Hence, the third side (H) is 13

Now, perimeter is P+B+H = 5+12+13

Perimeter=30cm
