Question

Area of an isosceles right triangle with side 9 cm as its one of the equal sides is:

​

Answer 1

isosceles right triangle implies that 9cm is the length of the two perpendicular sides since the length of hypotenuse can never be same as the length of any other side.

so area = 1/2 * base * height = 1/2 * 9 * 9 = 40.5
