Verify by measurement.​

Answer 1

Explanation:

AB=3.1

PQ is twice is AB

then,

PQ=6.2✓

Answer 2

Given that PQ is of length 3.1 cm.

We are to construct AB such that AB is twice that of PQ and vetify by measurement.

Let us firstly construct PQ with length 3.1cm.

Let us measure PQ with a compass and with respect to a reference point construct an arc on either.

Let us now join the two arc with a straight line.

This can when measured equals twice PQ = 6.2cm

Let us name the two points on this new line as A and B.
