Answer 1

where is the diagram

Answer 2

Thus, $ABCD$ is the required square.

Step-by-step explanation:

Given;

A square with a perimeter of $40cm$

For a square,all side are equal and all angle are $90degree$

So,

$4a=40$  where $a$ is side of square.

∴$a=10$

All side are $10cm$

Following steps:-

• Draw a line $AB=10cm$
• At point $A$ and $B$,draw angle $90degree$  and extend line like $AX$ and $BY$
• Take measure of $10cm$ and cuts the $AX$ and $BY$ from point $A$ and $B$ which is known as $D$ and $C$
• Join $C$ and $D$

Now $ABCD$ is the required square.
