Question

An isosceles right angled triangle has an area 8cm^2.Taking root2=1.414 find the value of semi perimeter of the triangle

Answer 1

Answer:

Equal sides of measure =10cm

Here, base and perpendicular are equal sides.

Area of a triangle =

2

1

×Base×Height

=

2

1

×10×10

=50

From Pythagorean Theorem:

Hypotenuse

2

= Base

2

+ Perpendicular

2

=10

2

+10

2

=200

or Hypotenuse =10

2

cm=10×1.41cm=14.1cm

Perimeter = Sum of all the sides =10+10+14.1=34.1

Therefore, Area of required triangle is 50cm

2

and perimeter =34.1cm
