Given: The sides 12 cm and 5 cm
To find: Area of triangle.
Solution:
- Now we have given that base is 12 cm and height is 5 cm.
- So by Pythagoras theorem, we have:
hypotenuse = √(base² + height²)
hypotenuse = √12² + 5²
hypotenuse = √144 + 25
hypotenuse = √169
hypotenuse = 13 cm
- Now s = a + b + c / 2 = 5 + 12 + 13 / 2
s = 15
- So area of triangle using herons formula is:
Area = √ s x (s - a) x (s - b) x (s - c)
Area = √ 15 x (10) x (3) x (2)
Area = √ 150 x 6
Area = √ 900
Area = 30 cm²
Answer:
So the area of right angled triangle is 30 cm².
