The rectangle shown is dilated by a scale factor of 2. ( Need Help). Will Mark Brainliest

Answer and Explanation:

If the rectangle is dilated by a scale factor of 2, that means that all of its sides are doubled.

(a) Originally, AB = CD = 15

So, we just multiply 15 by 2: 15 * 2 = 30. Now, A'B' = C'D' = 30 cm

Originally, AC = BD = 8

We just multiply 8 by 2: 8 * 2 = 16. Now, A'C' = B'D' = 16 cm

(b) Basically, the drawing will be of a new rectangle with dimensions of 30 cm by 16 cm.

30cm by 16cm

Step-by-step explanation:

this is because you are enlarging it by a scale factor and so you would just multiply the sides by the scale factor to get 30cm and 16cm

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

an equation by definition has to have two or more variables (x and 2 in this case)
