Question 819856: Square X is similar to square Y. The scale factor from square X to square Y is 2.5. The area of square X is 25 cm². What is the area of square Y? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x/y = 2.5
---
sx/sy = 2.5
sy = sx/2.5
---
ax = sx*sx = 25
ay = sy*sy
ay = sx/2.5*sx/2.5
ay = sx*sx/6.25
ay = 25/6.25
---
ay = 4 sq.cm
