Answer:
- Length = 42 m
- Perimeter = 168 m
Concept:
Here, we need to know how to find the area and perimeter of the square.
Area (square) = s²
Perimeter (square) = 4s
Solve:
<h2><u>PART I: Find the length</u></h2><h2><u /></h2>
<u>Given information</u>
Area = 1764 m²
<u>Given formula</u>
A = s²
<u>Substitute values into the formula</u>
1764 = s²
<u>Square root both sides</u>
√s² = √1764
![\boxed{s=42m}](https://tex.z-dn.net/?f=%5Cboxed%7Bs%3D42m%7D)
--------------------------------------------------------------------------------------------------------
<h2><u>PART II: Find the perimeter</u></h2>
<u>Given information</u>
s = 42 m
<u>Given formula</u>
P = 4s
<u>Substitute values into the formula</u>
P = 4 (42)
<u>Simplify by multiplication</u>
![\boxed{P=168m}](https://tex.z-dn.net/?f=%5Cboxed%7BP%3D168m%7D)
Hope this helps!! :)
