Question

The base of a right angle triangle measures 4 cm and its hypotenuse measure 5 cm . Find the area of the triangle.​​

Answer 1

Answer:

area = 6

Step-by-step explanation:

The 3rd side would be = (25 -16)^1/2 = (9)^1/2 = 3

area = 1/2 x b x h

= 1/2 x 4 x 3

= 6

Answer 2

In right-angled triangle ABC

  AB² + BC² = AC² (By Pythagoras Theorem) 

⇒  AB² + 4² = 5²

⇒  AB² = 25 – 16 = 9 5 cm 

⇒  AB = 3 cm

∴   Area of △ABC = 1/2 BC x AB = 1/2 x 4 x 3 = 6cm²
