Step-by-step explanation:
Let two sides of an isosceles right-angled triangle are of measure "a"
Area of triangle =200cm
2
. (given)
⇒200=
2
1
(a
2
)
⇒a=20cm
Now,
Hypotenuse
=
(a
2
+a
2
)
=
(2a
2
)
=
2
a
=20
2
=20×1.414
=28.28
⇒ Hypotenuse is 28.28cm
Perimeter of triangle = Sum of all the sides =2a+ Hypotenuse
=40+28.28
=68.28
⇒ Perimeter of triangle is 68.28cm.
