Question

The perimeter of the rectangle is 220m.if its length is 80m.what is the
measure of its width

Answer 1

Answer:

The breadth of the rectangle is 30 m.

Step-by-step explanation:

Given :  

Perimeter = 220 m  

Length = 80 m  

To find :  Breadth

Solution :

Let the breadth be y

★ Perimeter = 2(Length + Breadth)

⇒ 220 = 2(80 + y)

⇒ 220 = 160 + 2y

⇒ 2y = 220 - 160

⇒ 2y = 60

⇒ y = 60/2

⇒ y = 30

Breadth = 30

Therefore, the breadth of the rectangle is 30 m.

Answer 2

Given :

• Perimeter of Rectangle = 220m
• Length of Rectangle = 80m

To Find :

• Breadth of Rectangle

Solution :

★ Perimeter = 2(Length + Breadth)

⠀⟶⠀Perimeter = 2(Length + Breadth)

⠀⟶⠀220 = 2 × (80 + Breadth)

⠀⟶⠀220/2 = 80 + Breadth

⠀⟶⠀110 = 80 + Breadth

⠀⟶⠀110 - 80 = Breadth

⠀⟶⠀30m = Breadth

⛬ Breadth of Rectangle is 30m

What is Rectangle ?

• Rectangle is a shape with similar opposite sides, only 2 sides are equal. With 4 equal sides shape is called as square.

Properties :

• Properties of rectangle are :
• Opposite sides are equal and parrallel
• Opposite angles are equal.
• Adjacent angles are supplementary.
• Diagonals are equal.
• Each of the angles is a right angle.

Formulas :

• Perimeter = 2( l + b)
• Area = Length × Breadth
• Length = Area / Breadth
• Breadth = Area / Length
• Diagonal = √(l)² + (b)²
• l = Length
• b = Breadth
