Question

sahil has afield in a shape of rectangle. The length of the field is twice the breadth . The breadth is 80 m .Find the perimeter of the field.
a) 360 m
b) 480 m
c) 460 m
d) 520 m​

Answer 1

Answer:480

Step-by-step explanation:length is twice the breadth.

Breadth =80

80×2=160

Length=160

Perimeter of a rectangle=2(l+b)

=2(80+160)

=2(240)

=2×240

=480

Answer 2

Given,

• Sahil has a field a shape of Rectangle .
• The Length of the field is twice is the breadth.
• The Breadth is 80 m.

To Find,

• The Perimeter of the Field.

Solution :

⇒In this Question the Breadth is given = 80 m

And, The Length of the field is twice is breadth .

Therefore,

$\implies \sf{Length = 2 \times Breadth}$

$\implies \sf{Length = 2 \times 80}$

$\implies \boxed{\sf{Length = 160 \ m}}$

$\mapsto \underline{\sf{\pink{According \ to \ the \ Question :}}}$

║Length = 160 m And Breadth = 80 m║

Now We Find Perimeter of Rectangle :-

$\implies \sf{Perimeter \ of \ Rectangle = 2(Length + Breadth)}$

$\implies \sf{Perimeter \ of \ Rectangle = 2(160 + 80)}$

$\implies \sf{Perimeter \ of \ Rectangle = 2(240)}$

$\implies \boxed{\sf{Perimeter \ of \ Rectangle = 480 \ m}}$

Therefore,

$\boxed{\large{\bold{\red{Option Number - b)}}}}$

$\rule{200}2$
