Question

problem #1 - changing scales (mild)
if quadrilateral q is a scaled copy of quadrilateral p created with a scale factor of 3, what is the perimeter of q?

Explanation:

Step1: Calculate perimeter of P

$P_{P}=7 + 15+15 + 25=62$

Step2: Find perimeter of Q

Since scale - factor is 3, $P_{Q}=3\times P_{P}$
$P_{Q}=3\times62 = 186$

Answer:

186
