Question

. Find the perimeter of rectangle whose length and breadth respectively
a. 10m , 6m
b. 2.5cm, 750 m

Answer 1

Answer:

A) perimeter of rectangle

=2(l+b)

2(10+6)

2*16=32

= 32 m

B) 2.5 cm = 0.025m

perimeter of rectangle =

2(l+b)

2(0.025+750)

2*750.025

1500.05 m

Answer 2

Solution 1 :-

Given :

• Length = 10m
• Breadth = 6m

To Find :

• Perimeter of the Rectangle.

Solution :

↦ Perimeter of Rectangle = 2 ( l + b )

↦ Perimeter of Rectangle = 2 ( 10 + 6 )

↦ Perimeter of Rectangle = 2 × 16

↦ Perimeter of Rectangle = 32m

Solution 2 :-

Given :

• Length = 2.5cm = 0.025 m
• Breadth = 750m

To Find :

• Perimeter of the Rectangle.

Solution :

↦ Perimeter of Rectangle = 2 ( l + b )

↦ Perimeter of Rectangle = 2 ( 0.025 + 750 )

↦ Perimeter of Rectangle = 2 × 750.025

↦ Perimeter of Rectangle = 1500.05m

★ Additional Info :-

Formulas Related to Rectangle :

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