The length is 9m longer than breadth and perimeter is 54m
TO FINd
Find the breadth of rectangle
SOLUTIOn
**As we know that**
Area of rectangle = 2(length+breadth)
Perimeter of rectangle = 54 m
Let the breadth be x then length be x + 9
✞ According to the given condition
→ 2[x+(x + 9)] = 54
→ 2(x + x + 9) = 54
→ 2(2x + 9) = 54
→ 4x + 18 = 54
→ 4x = 54 - 18
→ 4x = 36
→ x = 36/4
→ x = 9
Hence,
Breadth = x = 9m
Length = x + 9 = 9 + 9 = 18m

Given:
Length is 9m longer than breadth and perimeter is 54m
Find:
Find the breadth = ?
Solution:
Let breadth be x
And let length be × + 9m
Area of rectangle = 2 (l+b)
ATQ,
=2× ( x + 9 + x ) = 54
= 2(2x + 9) = 54
= 4x + 18 = 54
= 4x = 54 - 18
= 4x = 36
= x = 36/4
= x = 9
Breadth = 9
