Question

a rectangle has a perimeter of 60 M if its length is twice its breadth what is its breadth?​

Answer 1

Answer:

it is very helpful to u..

Answer 2

Answer:

B=20 m

Step-by-step explanation:

As we have given in the question that the perimeter of the rectangle=60 m

We know that the perimeter=$2[l+b]$=60 m, Which is given in the

question and we have also given that its length is twice its breadth i.e. b=2l

So we solve for breadth

$l+b=30$

=$l+2l=30${ as the value of b=2l]

=$3l=30$

$l=10$

$b=20$

Therefore the final answer would be that breadth=20 m
