Question

two brothers have a triangular plot decided to the distribute equally among themselves but also want to donate equal area of the share of the part to a school which makes a triangular part which is attached to the base side of 120 M of the triangle plot

Answer 1

We know that a median divides a triangle in two triangle of equal area.
Similarly here we can divide the base into 3 equal parts and join it to the remaining vertex. So,vwe get three equal parts.
Each of the three triangles will have a base =120%3 m
=40m.
