Question

Two sides of a shape are drawn here. Complete the shape by drawing two more sides so that its area is $2$ square cm.

Answer 1

Clearly the area is 2 square cm since the figure consists of 4 triangles each having base = 1 units and height = 1 units

Area of each triangle = 1/2 sq cm

so area of shape containing 4 such triangles = 2 sq cm
