Answer:
The scaled factor is 3.
Step-by-step explanation:
Consider the figure shown below:
It is given that: A rectangle N has an area of 5 square units. James drew a scaled version of Rectangle N and labeled it Rectangle P.
We need to find the scale factor which is used by James.
First, we will calculate the area of Rectangle P by counting the number of squares shown in the figure.
Area of rectangle P = 45 square unit
Let x be the scaled factor.
To scale the rectangle we need to multiply both the length and breadth of the rectangle N by x and the scaled area should be equal to 45.
![[x\times \text{Length} ][x \times \text{breadth}]=45](https://tex.z-dn.net/?f=%5Bx%5Ctimes%20%20%5Ctext%7BLength%7D%20%5D%5Bx%20%5Ctimes%20%20%5Ctext%7Bbreadth%7D%5D%3D45)

It is given that area of the rectangle N is 5 square units, so put length time breadth as 5.



Hence, the scaled factor is 3.
