Question

Find the area of an isosceles right triangle whose hypotenuse is 18 cm​

Answer 1

Answer:

Refer to the attachment above. Hope it helps

Answer 2

Answer:

9 cm

Step-by-step explanation:

Since the triangle is isosceles right triangle, base is equal to height.

Given, hypotenuse is 18 cm

Let base = height x cm

According to Pythagoras Theorem, (base^2)+(height^2)=(hypotenuse^2)

Therefore, (x^2)+(x^2)=(18^2)

Implies that, 2(x^2)=324

Implies that, (X^2)=324/2

= 162

Implies that, x= Square root of 162

=9root2

Now, Area = 1/2*base*height

Since base=height

Area = 1/2*9root2 *9root2

= 9 cm square.
