Question

If the area of an isoceles right triangle is 8 cm.what is the perimeter

Answer 1

we know that In isoceles triangle 2 sides are equal
and one angle given is 90°
by applying Pythagoras we can find third side
let triangle be ABC
ANGLE B=90
therefore AC^2=BC^2+AB^2
8^2+8^2=AC^2
AC^2=128
AC =11.3
peri=sum of all sides
8+8+11.6=27.6
therefore perimeter of triangle is 27.6
their may be slight chnge in answer due to decimal point......
hope this will help u..
