Hi there, I believe the answer to the last statement is TRUE. The difference between the two unshaded parts is 18 cm², which is the combined area of triangles 1, 2, and 3. Since these triangles are identical, each one has an area of 6 cm². Triangle EFD comprises of 4 identical triangles, so its area is 24 cm².
Yes. Think you are right.
I missed the 18cm² is actually equal to area of triangle 1,2 & 3.
I was wondering if area of triangle ABC is not 6 cm² but given different is 18 cm² then area of ABC = 6 cm².
Thank you for your explanation.
