What he said because. And so yea
Let
x-------------> length of the side of a square
[area of a square]=x*x------> x²
[area of rectangle]=[shorter side]*[<span>longer side]
</span>[shorter side]=0.90 x-------> (<span>is 10% percent less than the length of a side of square)
</span>[longer side]=1.10x-------> (<span>is 10% percent more than the length of a side of square
</span>
[area of rectangle]=(1.10x)*(0.90x)-----> 0.99x²
[the ratio of the area of rectangle to the area of square]=0.99x²/x²=0.99
the answer is
the ratio of the area of rectangle to the area of square is 0.99
A. the relation is a function
