Let the length =x
Breadth=18cm
Perimeter=86cm
Perimeter = 2(l+b)
86=2(x+18)
86=2x+36
2x=86-36
2x=50
X=50/2
X=25cm
Length = 25cm

Solution -
Given Data -
Perimeter = 86 cm
Width = 18 cm
∵ Here, we need to find the length of a rectangle when the perimeter and width is given
∵ Perimeter of rectangle
= 2(length + breadth)
Let's assume the length as x cm
According to Question,
Perimeter of rectangle = 86 cm
2(x + 18) = 86
⇒ x + 18 = 86/2 = 43
⇒ x = 43 - 18
⇒ x = 25
Measurements -
Length = x cm = 25 cm
∴ Length of the given rectangle is 25 cm
