Question

p is a rectangle with length 40 cm and width x cm q ia a rectangle with width y cm

Answer 1

Answer:

25 : 18

Step-by-step explanation:

complete question is in picture attached

Length of P = 40 cm

Length of Q is 25 % more than P

length of Q = 40 + (25/100)*40 = 50 cm

Area of P = 40x cm²

Area of Q = 50 y cm²

Area of Q is 10% less then Area pf P

Area of Q = Area of P - (10/100) Area of P

=> Area of Q = (90/100)Area of P

=> 10 * Area of Q = 9 * Area of P

=> 10 * 50y = 9 * 40 x

=> 50y = 36x

=> x/y = 50/36

=> x/y = 25/18

=> x: y :: 25 : 18
