Question

The square READ with RE=5.1 cm.

Answer 1

Step-by-step explanation:

We know sides of square are equal. Thus RE=EA=AD=RD=5.1 cm.

First draw a line segment, then measure 5.1 cm in rounder and mark the arcs. This is line RE=5.1 cm.

Then using protactor mark 90°

 and again mark 5.1 cm on that line segment. This is EA.

Again mark 5.1 cm in protactor and make line AD.

At last join points D and R.
