If you see in 2 nm is mid point os triangle abc So nm = 1/2 bc =4 & MP is mid point of triangle ABC So mp = 1/2 ba = 3 nm = bp nb = mp Angle b = 90° Hence , bpmn is a rectangle
Area of triangle anm = 1/2 × base × height = 3×4×1/2 = 6cm Area of triangle mpc = 1/2 ×base × height = 1/2 ×4 ×3 = 6cm Hence area of shaded portion = 6+6 cm =12cm

So nm = 1/2 bc =4
& MP is mid point of triangle ABC
So mp = 1/2 ba = 3
nm = bp
nb = mp
Angle b = 90°
Hence , bpmn is a rectangle
Area of triangle anm = 1/2 × base × height
= 3×4×1/2 = 6cm
Area of triangle mpc = 1/2 ×base × height
= 1/2 ×4 ×3 = 6cm
Hence area of shaded portion = 6+6 cm =12cm
