Answer 1

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
