Question

4.
The length of a rectangle is 2 times its breadth. The
perimeter of
is 36m. Find its length &
breadth​

Answer 1

Answer:

Length= 12cm

Breadth= 6cm

Step-by-step explanation:

Let the breadth be x

Then the length is 2x

Perimeter= 36cm

Perimeter= 2( L + B)

36= 2(2x+2)

36÷2= x+2x

18=3x

x= 18÷3

x= 6

Therefore Length= 12cm

Breadth = 6cm

Answer 2

Answer:

length=12m

breadth=6m

Step-by-step explanation:

let the breath be = x

so lengeth =2x

perimeter of reactangel=2(l+b) =36m

2(2x+x)=36m

2(3x)=36m

6x=36m

x=36/6

x=6m

it means breadth=x=6m

and length=2x=12m
