Raj dropped paint on the drawing of a shape. What shape could it be?

• A square

• A triangle

• A rectangle

• It can be a square or a rectangle

Answer explanation

We can see 3 sides of the shape. The paint seems to be covering the 4th side - so the shape cannot be a triangle. We do not know if all sides are equal or not so the shape could be a square OR a rectangle - both are possible.
