Answer:
Area of a triangle = area of rectangle
Step-by-step explanation:
Given:
Height of triangle = n cm, Base of triangle = m
Length of rectangle = n cm, Width of rectangle = m cm
Area of ΔTRI = base × height
= ( m ) × (n) ⇒
mn
Area of Rectangle RECT = Length × Width
= m × n ⇒ = mn
Comparing Area of triangle and rectangle.
mn = mn
We can conclude that area of triangle is half of the area of rectangle.
