Can someone tell me the answer to this?
1. The scale of two similar quadrilaterals is 1:2. The perimeter of the smaller quadrilateral is 80 centimeters. What is the perimeter of the larger quadrilateral?
A. 40cm
B. 80cm
C. 160cm
D. 320cm
THANKS! (link)

Basically, if the scale is 1:2, then each side of the larger quadrilateral is twice the length of the corresponding side of the smaller quadrilateral. So you just take the perimeter, 80 cm, times 2, which is 160 cm. Therefore, the answer is C.
