Question

Suppose Enrique has two building blocks. The area of one face of one of the blocks is 4 square centimeters and the area of the face of the other block is 100 square centimeters. What is the scale factor from the smaller block to the larger​ block?

Answer 1

The Scale factor is 5.

Explanation:

Because the area has cm^2 to find the scale factor you find the number it takes to get from one area to the next and take the square root.

4X = 100

X = 100/4

X = 25 (Take the sqrt because of area)

X = sqrt(25)

X = 5

The Scale factor is 5.

Answer 2

1:25

Explanation:

Scale factor= 1:25
