Question

The perimeterof a rectangular sheet is 120 cm if the length is 25 cm find it breath

Answer 1

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

Answer 2

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
