Answer:
given:perimeter of rectangle=1m
=100cm
And one side is 5cm long than the other.
Let the other side be: x
Then first side will be =x+5
As we know,
perimeter of rectangle= 2(l+b)
100cm=2(x+x+5)
100cm=2(2x+5)
100cm=4x+10
4x=100-10
4x=90
therefore x=90/4
=22.5cm
first side =22.5cm. ans.
second side=22.5+5
27.5cm. ans.

Answer:
perimeter (p)= 1m=100cm
Taking length as =x
breadth as =x+5
Step-by-step explanation:
2(x+(x+5) )= 100
2x+2x+ 10=100
4x+10=100
4x=100-10= 90
x=90÷4 = 22.5
x= 22.5
therefore, length = 22.5 cm
breadth=x+5=22.5+5
b = 27.5
2(22.5+27.5)=100
