Answer:
In Δ CFD , CD is the LONGEST side.
Step-by-step explanation:
Here, the given Δ CSD is a RIGHT ANGLED TRIANGLE.
Now, as we know in a right triangle, HYPOTENUSE IS THE LONGEST SIDE.
So, in Δ CSD SD is the longest side as SD = Hypotenuse.
Now, an altitude CF is drawn to hypotenuse SD.
⇒ CF ⊥ SD
⇒ Δ CFD is a RIGHT ANGLED TRIANGLE with ∠ F = 90°
and CD as a hypotenuse.
⇒ In Δ CFD , CD is the LONGEST side.
Hence, CD is the longest side in the given triangle CFD.

Answer:
648cm2
Step-by-step explanation:
2(1/2×12×24)+3(12×10)
=288+360
=648 cm2
Answer:
68.1 units²
Step-by-step explanation:
Start by finding the area of the rectangle...
Then, find the area of the semicircle...
Now, add the two to get...
54+14.1=68.1
I think the answer would be 4^4
Because 9-5 =4 not sure though
