5. The largest mosaic in the world is on the walls of the central library of the
Cloud [144]

Answer:

<h3> 63.25m</h3>

Step-by-step explanation:

The area of the square wall = L² where;

L is the length of the wall.

Given

Area of the mosaic = 4000m²

Substitute into the formula and get L

4000 = L²

Square root both sides

√4000 = √L²

√4000 = L

Rearrange

L = √4000

L = 63.25m (to the nearest hundredth)

<h3>Hence the length to the nearest hundredth is 63.25m</h3>
