Question

The area of triangle in which AB=BC=4cm and angle b=90. (1). 16cm^2 (2) 8 cm^2, (3) 4 cm^2, (4) 12 cm^2.

Answer 1

AB is the height of the right angled triangle,
⇒ area of triangle = 1/2 * 4* 4
                             = 2 * 4
                              =8 cm2
∴ option 2 is correct.
