Find the area of a right-angled triangle whose base is 12 cm and hypotenuse is 13cm.

Q: Find the area of a right-angled triangle whose base is 12 cm and hypotenuse is 13cm.

Height of the triangle = 13 2 - 12 2 = 25 = 5 cm. Its area = 1 2 * b a s e * h e i g h t = 1 2 * 12 * 5 = 30 c m 2 .

30
40
50
60

Correct Answer: 30

Explanation:

Height of the triangle = $132 - 122 = 25$ = 5 cm.

Its area = $\frac{1}{2} * b a s e * h e i g h t$ = $\frac{1}{2} * 12 * 5$ = $30 c m 2$ .
