Question

PLEASE HELP!!

Given: line segment AB is 10 inches long.


Find the length of A'B' if AB is dilated to form A'B' with a scale factor of 2.


A) 1/2 inches

B) 5 inches

C)10 inches

D)20 inches

Answer 1

D or 20

Explanation:

If the scale factor is 2 then you take the original number, 10, and multiply it by 2.

10*2=20

Answer 2

Option D). 20 inches

Explanation:

Length of AB which is of length = 10 inches.

If the length of AB is dilated to form A'B' with a scale factor of 2, then we have to find the length of A'B'

Since we know the formula of dilation as

New dimension = Scale factor × Old dimension

So A'B' = Scale factor × AB

A'B' = 2× 10 = 20 Inches

Option D). 20 inches is the solution.
