Answer:

Given =A, B, C are midpoint of DE, EF, DF respectively

To find=rotio of area tri ABC and tri DEF

SOL) 2AB=DF(midpoint theorm)

Step-by-step explanation:

similarly 2BC=DE, 2AC=EF

SO tri ABC SIMILAR tri DEF(SSS similarity)

The area of similar triangles are equal to the ratio of their corresponding sides

Area of tri ABC/area of triDEF=[AB/DE] ²

=(1/2)²/1²=1:4
