I got 6 for my answer, but I'm not 100% sure if I'm right.
6(2x-11)+15=21
12x-66+15=21
12x-51=21
+51 +51
12x=72
----- ----
12 12
x=6

The new length and width is 48in and 40in respectively
<h3>Dilation</h3>
Given the following information
- Width = 25in
- Length = 40in
If the length and the width are dilated by a factor of 1.2, the new length and width is expressed as;
W = 25(1.2) = 30in
L = 40(1.2)
L = 48 in
Hence the new length and width is 48in and 40in respectively
