Answer:
X:Y = 3/20
Step-by-step explanation:
Given -
Length of rectangle P = 80
Width of rectangle P = X
Length of rectangle Q, Y = 25% more than the length of rectangle P
Length of rectangle Q = 1.25 X
Width of rectangle Q = 9
Area of rectangle P = 80X
Area of Q = 0.75 % of area of rectangle P
Area of Q = 0.75 * 80X = 60 X
or 9Y = 60 X
X:Y = 9/60
X:Y = 3/20
