Qouadrilateral A has side length 6,9,9 and 12 quadrilateral B is a scaled copy of quadrilateral A, with its, shortest side of le

The perimeter of quadrilateral B is 12.

Explanation

Quadrilateral A has side lengths as 6, 9, 9 and 12. In quadrilateral B, length of the shortest side is 2.

As quadrilateral B is a scaled copy of quadrilateral A, so the scale factor will be...

(Shortest side of B / Shortest side of A) $=\frac{2}{6}=\frac{1}{3}$

Now the remaining side lengths for quadrilateral B will be.....

$(9*\frac{1}{3}) , (9*\frac{1}{3})$ and $(12*\frac{1}{3})$

⇒ 3 , 3 and 4

Thus, the perimeter of quadrilateral B is $= 2+3+3+4= 12$

Please include the steps that took you to get your answer. I am very confused on what to do with the 1/2.

First let's review how to expand this!

(ax+b)^2=a^2*x^2+2abx+a^2

In this case

(2x^2+1/2)^2=2^2*x^2+2*1/2*2x+(1/2)^2

=4x^2+2x+1/4

Done!
