Answer:
A
Step-by-step explanation:
Length : 
Perimeter: 
Perimeter = 2(Length + Width)
15x + 17y = 2(
+ Width)
15x + 17y = 7x + 14y + 2(Width)
15x + 17y -7x -14y = 2(Width)
8x + 3y = 2(Width)
Width = 
Width = 4x + 3y/2
if you reduce it you will get 9/11
You write it as 46 divide by 1058. 46 x 2 is the closest you will get to 100. 46 x 2 is 92. put it in and you have 138 left. multiply 46 x 3 and you will get 138. amswer is 23. remember to bring down the next number whwn dividing
