Question

The perimeter of a rectangle with length 45 m and breadth 42 m is

a)180 m
b)174 cm
c)176 m
d)174 m​

Answer 1

Answer:

Lenthg =45×2=90

breadth=42×2=84

90+84=174 Cm Ans

Answer 2

Given :-

• Length = 45m
• Breadth = 42m

To Find :-

• Perimeter of the Rectangle

Formula :-

• 2 ( Length + Breadth )

Solution :-

⇒ Perimeter = 2(Length + Breadth)

⇒ Perimeter = 2 ( 45 + 42 )

⇒ Perimeter = 2 × 87

⇒ Perimeter = 174m

________________

So, Perimeter is 174m

Formulas Related to Rectangle :-

• Area = Length × Breadth
• Perimeter = 2(l + b)
• Length = Area/Breadth
• Breadth = Area/Length
• Diagonal = √l² + b²
