Question

Find the perimeter of a rectangular field of length 36m and breadth 28m.​

Answer 1

ANSWER :

• ❒ The perimeter of a rectangular field of length 36 m and breadth 28 m is 128 m.

__________________________________________________________

SOLUTION :

❍ Given :-

• Length of the rectangular field = 36 m

• Breadth of the rectangular field = 28 m

❍ To Find :-

• Perimeter of the rectangular field = ?

❍ Required Formula :-

• ★ Perimeter of a rectangle = 2 (Length + Breadth) ★ •

_____________________________________

❍ Calculation :-

Using the formula of Perimeter of a rectangle, we get,

• ★ Perimeter = 2 (Length + Breadth)

➨ Perimeter = { 2 (36 + 28) } m

➨ Perimeter = ( 2 × 64 ) m

∴ Perimeter = 128 m ★

• Hence, Perimeter of the rectangular field is 128 m.

$\mathfrak{Solution-:}$

Given-:

• Length of a Rectangle = 36m
• Breadth of a Rectangle = 28m

To Find-:

• Perimeter of a Rectangle = ?

Using Formula-:

• Perimeter of a Rectangle = 2 ( Length + Breadth )

Calculation-:

Perimeter of a Rectangle = 2 ( Length + Breadth )

↦2 ( 36m + 28m )

↦2 (64m²)

↦128m²

Hence, the Perimeter of a Rectangle is 128m².

MORE TO KNOW-:

★ Perimeter-: Perimeter of a closed figure is the sum of lengths of all the sides.

↦Rectangle

Perimeter of a Rectangle = 2 (Length + Breadth)

↦Square

Perimeter of a Square = 4 × Side

↦Equilateral Triangle

Perimeter of a Equilateral Triangle = 3 × Side of a Triangle

______________________________

★ Area-: Area of a closed figure is the amount of region or plane enclosed by it.

↦Rectangle

Area of a Rectangle = Length × Breadth

↦Square

Area of a Square = (Side)²

↦Irregular Figure-: Area of Irregular figures is calculated using following steps:

Step 1: Count full squares, half squares and more than half of squares covered by the figure separately.

Step 2: Area covered by a full square and more than half of a square is counted as 1 sq. unit.

Step 3: Area covered by half of a square is counted as 1/2 sq. unit.

Step 4: Portions that covers less than half of a square are ignored.
