let length and breadth of rectangle is l and b
and side of square is a
according to question
l-l*50%=b+b*25%=a(it becomes square when length and breadth are equal)
l-l/2=b+b/4=a
l/2=5b/4=a
perimeter of rectangle is =2(l+b)
perimeter of square is = 4*a=4*l/2=2l
or. 4*a=4*5b/4=5b

Answer:
- Length - 50% = 1/2
- Breadth - 25% = 1/4
- Perimeter of Rectangle & Square
- Area of Rectangle & Square
- Perimeter of Rectangle - 2×(Length + Breadth)
- Area of Rectangle - Length × Breadth
- Perimeter of Square - 4 × Side
- Area of Square - Side × Side
Let the Rectangle be,
Length - x
Breadth - y
