Question

Perimeter of a rectangle is 260 centimetres if its length is 30m more than its breadth find its length.
​

Answer 1

Given :-

• Shape = Rectangle
• Perimeter of Rectangle = 260cm
• Its length is 30 metre more than its breadth.

To Find :-

• Length of the Rectangle

Solution :-

In the Question it was given that the Length of the Rectangle is 30m more than its breadth, Therefore

⟶ Let Breadth of Rectangle be x

⟶ Let Length of Rectangle be x + 30

According to the Question :-

⟹ Perimeter = 2 ( Length + Breadth )

⟹ 260 = 2 ( x + 30 + x )

⟹ 260 ÷ 2 = x + 30 + x

⟹ 130 = x + 30 + x

⟹ 130 = 2x + 30

⟹ 130 - 30 = 2x

⟹ 100 = 2x

⟹ 100 ÷ 2 = x

⟹ 50 = x

Therefore:-

• Length of Rectangle = x + 30 = 50 + 30 = 80cm
• Breadth of Rectangle = x = 50cm

★ Additional Info :

• Formulas Related to Rectangle :
• Perimeter of Rectangle = 2( l + b)
• Area = Length × Breadth
• Length = Area / Breadth
• Breadth = Area / Length
• Diagonal = √(l)² + (b)²
