The area of square flake of gold is 
<h3><u>Solution:</u></h3>
Given that width of square flake of gold is
millimeter
To find : Area of square flake
Since gold flake is in shape of square, we can use area of square formula
<em><u>The formula for area of square is given as:</u></em>

where "s" is the length of one side

Hence , the calculated area of flake is 
take the breadth as x and accordingly length as (x+18)
the formula for finding the perimeter of a rectangle is 2(l+b) now put the correct values as shown in the picture and form an equation this way you will be able to find x which is the breadth and length Is 18 morethan breadth ,now as u have found both length and breadth go ahead and find the area whose formula is length×breadth
