jafar has an isosceles triangle with an area of 20.25cm squared, what is the length of the side facing the right angle?

Answer 1

The only isosceles truiangle that has a right angle is a 45-45-90 degree triangle. It is half a square of 40.5 cm^2 area, divided along a diagonal.
The equal side lengths would be sqrt40.5 = 6.364 cm
The hypotenuse would be that times the square root of 2, or 9.00 cm

Answer 2

thNKS!

Answer 3

The answer is exactly nine, since
sqrt(40.5)*sqrt(2) = sqrt(81)

I should have seen that.

You're welcome!
