Answer 1

Answer:/ is Irrational while A is Rational

Step-by-step explanation:

ABC is Right Angle Triangle.

In Which

Base (BA)=2√2

Hypotenuse(CA)=√10

Height(CB)=?

Using Phythagoras Theroem

Hypotenuse²=Base²+Height ²

Filling Information Given Above in Theroem.

√10²=(2√2)²+height ²

10=4×2+height ²

10=8+height ²

10-8=height ²

2=height ²

height=√2

So We get

Base=2√2

Height=√2

Hypotenuse=√10

Perimeter=Sum of All Side

Perimeter of Given Triangle=2√2+√2+√10

Perimeter=3√2+√10

Perimeter That Is Represented by / is a Irrational.

Now Area of Triangle

=1/2×base×height

=1/2×2√2×√2

=√2×√2

=2

So Area Represented by A is a Rational

SO Option C is Correct
