Question

If the area of an isosceles right triangle is 8 cm", then the perimeter of the triangle is​

Answer 1

Answer:

8+4√2 cm

Step-by-step explanation:

We know that area of an isosceles right triangle is 1/2 ×a^2, where a is the equal side.

•°• A. T. Q,

1/2× a^2 = 8

Solving for a, we get a= 4 cm

Thus the hypotenuse of Isosceles right triangle =√(a^2+a^2)

=a√2

=4√2 cm

•°• The perimeter of triangle= a + a + a√2

= 4+4+4√2

=8+4√2 cm
