👉 Represent root 4.7 on Number line geometrically
Step 1)
Draw a line A B that is 4.7 in length, and then add 1 to C so that the distance from A to C is 5.7.
Step 2)
From the midpoint of A C on the line, use your compass and make a half circle from A to C.
Step 3)
Draw a vertical line up from B until it touches the red half circle you made in Step 2.
Step 4)
From B on the number line, use your compass and make a quarter circle from D to E.
The square root of 4.7 is the distance from B to E. To make things clearer, we have also created the illustration below showing where B, E, and the square root of 4.7 are located on the number line, labeled with numbers instead of the half circle, quarter circle and vertical line.
