Question

sahil has a field in the shape of a rectangle. the length of the field is twice it's 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 c.m is the perimeter of the field

Step-by-step explanation:

given breath = 80

then from question length = 160

perimeter = 2× ( 80 + 160)

perimeter = 480 c.m

Answer 2

$\bold{\underline{\underline{\huge{\sf{AnsWer:}}}}}$

Perimeter of the field is 480 m.

$\bold{\underline{\underline{\large{\sf{StEp\:by\:stEp\:explanation:}}}}}$

GiVeN :

• A rectangular shaped field
• The length of the field is twice it's breadth
• Breadth is 80 m

To FiNd :

• Perimeter of the field

SoLuTioN :

We have the breadth of the field, 80 m.

Given that the length of the field is twice it's breadth.

$\sf{\therefore{Lengt\:=\:2\:\times\:breadth}}$

Block in the value,

$\hookrightarrow$ $\sf{Length\:=\:2\:\times\:80}$

$\hookrightarrow$ $\sf{Length\:=\:160m}$

We have the measure of length and breadth.

Substituting the value in the formula of perimeter of the rectangle, we can find the perimeter.

Formula :

$\bold{\large{\boxed{\boxed{\sf{\green{Perimeter\:=\:2\:(length\:+\:breadth)}}}}}}$

Block in the values,

$\hookrightarrow$ $\sf{2\:(160\:+\:80)}$

$\hookrightarrow$ $\sf{320\:+\:160}$

$\hookrightarrow$ $\sf{480}$

$\sf{\therefore{Perimeter\:of\:the\:rectangular\:field=\:480m}}$
