Question

The length of a rectangle is twice of its breadth if its perimeter is 48 cm find the dimension of the rectangle?​

Answer 1

Let, the dimensions of the rectangle be

x

c

m

,

y

c

m

respectively

Given that,

x

=

2

y

and Perimeter

=

48

c

m

i.e.,

2

(

x

+

y

)

=

48

⟹

2

(

2

y

+

y

)

=

48

⟹

6

y

=

48

⟹

y

=

48

6

=

8

and

x

=

2

y

=

2

×

8

=

16

∴

the dimensions of the rectangle are

16

c

m

,

8

c

m

respectively
