Question

Find the perimeter of an isosceles right angled triangle having an area of 200 cm square

Answer 1

Answer:

Step-by-step explanation:

Area= 200 cm2

P=?

Area= 1/2bh

200=1/2bh

200*2=BH

400 = BH

It is a isosceles ∆

So b=h

So b+b=400

2b=400

B=400/2. =200

So b = 200 and h=200

A is the hyptneus

So by pythegorams theorem

A^2=b^2+h^2

=200 ^2+200^2

40000+40000=80000

A^2=80000

A=√80000

So a=282.2

P=b+h+a

=200+200+282.2=682.2 cm
