Question 589272
The perimeter of pqrs is 9m + 12m + 9m +6m = 36m
Sides qr and xy are corresponding sides, and their lengths are 12m and 8 (in mystery units)
The ratio of sides of wxyz to pqrs is 8/12m, so the ratio of their perimeters is the same, and the perimeter of wxyz is
{{{(36m)(8/12m)=36*8/12=24}}}
The perimeter of wxyz is 24 in whatever units the length of side xy was given.
