b/l = 2/3
where l is length and b is breadth
so l= 1.5 b
2(l+b)= 50
l+b=25
on subsisting the value of l
we get
1.5b + b = 25
2.5b = 25
b= 10
so l= 15
given the altitude is 10
so area = longest side * altitude
area =15*10= 150 cm²

Answer:
150
Step-by-step explanation:
Let the ratio constant be x
According to question
2x+3x+2x+3x=50
10x=50
x=5
Sides=10 and 15
Area of parallelogram=base *height
10*15=150
