Answer:

Construction: CE

When Area = 4 sq cm

=> Side^2 = Area

=> Side = 2 cm

Thus, AD = 2 cm

AE = 2/2 = 1 cm [median]

Area of triangle ADE = 1/2 × bh = 1/2 × 2 × 1 = 1 sq cm

Similarly, Area of triangle EBC is also 1 sq cm

Area of triangle EDC = 4 - 1 - 1 = 2 sq cm

Area of FCD = 1/2 × Area of triangle EDC

Area of GDC = 1/2 × Area of triangle FCD

Area of HCD = 1/2 × Area of triangle GDC

Area of KDC = 1/2 × Area of triangle HCD

Thus, Area of KDC = 1/2 × 1/2 × 1/2 × 1/2 × 2 = 1/8 sq cm

Property used: The median divides the triangle into two parts of equal area.
