The length of Q = 40 x 1.25 =50

The area of Q =50y cm^2

The area of P =40x cm^2

40x * 0.90 = 50y

36x = 50y, solve for x/y

x/y = 50 / 36 =25 / 18

So, the ratio of x : y =25 : 18. This does make sense because:

Area of P =40 x 25 =1,000 cm^2, and:

Area of Q =50 x 18 =900 cm^2 - which is 90% of area of P.
