The ratio x:y as required in the task content is; 25:18.
It follows from the information given in the task content that;
The area of rectangle P is; 40x.
The area of rectangle Q is; y × (1.25 × 40) = 50y.
Hence, since the area of Q is 10% less than the area of P, it follows that A(q) = 0.9A(p).
And, A(p)/A(q) = 10/9
Hence, 10/9 = 40x/50y
x/y= 50/36 = 25/18
Hence, the required ratio is; 25: 18.
