Answer:
Step-by-step explanation:
Area of square = x^2
If length is multiplied by 3, then each side of square is now 3x
new Area = (3x)^2 = (3x)*(3x) = 9x^2
So the Area has increased by a factor of 9.
In general, the Area will always increase by a factor which is the square of the factor applied to the side length.

Answer: 1346cm
Step-by-step explanation:
From the question, we are informed that Reagan has a rectangular bedspread that measures 238 centimeters by 435 centimeters and that he wants to sew a fringe around the edge of the bedspread.
This simply means that we have to find the perimeter of the rectangular bedspread and this will be:
= 2(length + width)
= 2(435 + 238
= 2(673)
= 1346cm
The length of fridge needed by Reegan is 1346cm.
