Question

Construct a line segment of length $12.4cm$. Divide this line into $4$ equal parts and find the length of each part.

• A. $3.1cm$
• B. $4.1cm$
• C. $3.0cm$
• D. $4.0cm$

Answer 1

The correct option is A $3.1cm$

1.Draw a line $PQ$ $=12.4cm$.
2. Draw perpendicular bisector of PQ. Which interest PQ at O
3. Then draw perpendicular bisector of $PO$ and $QO$. Where they intersect $PQ$ name that point as $A$ and $B$ respectively.
4.PA, AO, OB, BQ are the 4 equal parts.

5. measure each part that comes out to be $=3.1cm$
