Question

the length of the rectangle is twice its breathe if the perimeter of rectangle is 180m find its dimenisions​

Answer 1

Answer:

let

breadth = b

thus length = 2b

Thus perimeter = 2(l+b)

P = 2(l+b)

180 = 2(2b+b)

180 = 2(3b)

180 = 6b

b = 30m

Thus ;

breadth = b = 30m

length = 2b = 60m it is the right answer ..........if you like this so follow me plz .........i do very good answer of all question...........

Answer 2

Answer:

breadth = 30m

length = 60m

Step-by-step explanation:

let the breadth be x

so length is equal to 2x

perimeter=2(length + breadth )

2(x+2x)=180

x+2x =90

3x=90

x=30

therefore, x=30

2x=60
