Answer:
Area of a triangle = [tex]\frac{1}{2}[/tex] 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 = [tex]\frac{1}{2}[/tex] base × height
= [tex]\frac{1}{2}[/tex] ( m ) × (n) ⇒ [tex]\frac{1}{2}[/tex] mn
Area of Rectangle RECT = Length × Width
= m × n ⇒ = mn
Comparing Area of triangle and rectangle.
[tex]\frac{1}{2}[/tex] mn = mn
We can conclude that area of triangle is half of the area of rectangle.
