Answer 1

Answer:

area of the triangle is 33.33cm^2

Answer 2

Answer:20

Step-by-step explanation:

Let the small side be ‘x’,so given that the other side is twice the small side so it will be ‘2x’

As it is a right angled triangle

By Pythagorean’s theorem

X^2+(2x)^2=10^2

X^2+4x^2=100

5x^2=100

X^2=20

X=(20)^1/2

2x=2(20)^1/2

W.K.T

Area of a right angled triangle is

1/2(product of its legs)

:.1/2((20)^1/2 •2(20)^1/2)

1/2(2•20)

=20
