Question

The length of a rectangular field is twice times its breadth. If the breadth of the rectangle is 4.5 m, find the perimeter of the rectangle ?​

Answer 1

Answer:

☆perimeter of rectangle:

$\boxed{\bf{\green{perimeter = sum\;of\;all\;sides}}}$

$\boxed{\bf{\green{perimeter = 2(length+breadth) }}}$

☆Solution:

》length = 2× breadth

》breadth= 4.5m

$\rightarrow{\sf{perimeter= 2(l+b)}}$

$\rightarrow{\sf{perimeter= 2(2b+b)}}$

$\rightarrow{\sf{perimeter= 2(3b)}}$

$\rightarrow{\sf{perimeter= 2×3×4.5}}$

$\rightarrow{\bf{perimeter= 27m}}$

Answer 2

Answer:

27

Step-by-step explanation:

Given: Breadth=4.5

length=2xbreadth

length=2x4.5

length=9

perimeter=sum of all sides

perimeter=2(lenght X breadth)

perimeter=2(9+4.5)

perimeter=2 X 13.5

perimeter=27
