Question

Find the area of right angled triangle whose hypotenuse is 15 and base is 9 cm.

Answer 1

Answer:

54 cm²

Step-by-step explanation:

Hypotenuse² = base² + height²

15² = 9² + x²

x = 12 by solving ⇒ height = 12 cm

The area of a right angled triangle is $\frac{1}{2} * base * height$

Hence the area of a triangle is $\frac{1}{2} * 9 * 12 = 54 cm^{2}$

Answer 2

Answer:

Altitude=12

Step-by-step explanation:

base²+Altitude²=Hypotenus²

9⁹+Altitude=15²

Altitude=15²-9²

Altitude=225-81

Altitude =144

root of 144=12

Altitude =12
