The ratio of square h’s length to square i’s length is 3 : 5. if the length of square h is 18 meters, what is the perimeter of square i? a. 60 meters c. 90 meters b. 54 meters d. 120 meters

B. 54 meters

first you want to set up your ratios and cross multiply to figure out the number to square l's ratio. which would be 10.8.

then use formula for perimeter 
2(l)+2(w)=9
2(10.8)+2(18)=53.6-rounded =54

Ask google i believe they can you with that question
