p=120cm
l=25cm
b=?
formula of perimeter of rectangle =2(l+b)
2(25+x)=120
50+2x=120
120-50=2x
70=2x
x=70÷2
x=35
l=25cm

Length + Length= 25cm + 25cm
= 50 cm
So now, 120 - 50 = 70
then, 70 = Breadth + Breadth
So, 70÷2= 35
Thus, the breadth of the rectangular sheet is 35 cm
= 50 cm
So now, 120 - 50 = 70
then, 70 = Breadth + Breadth
So, 70÷2= 35
Thus, the breadth of the rectangular sheet is 35 cm
