Question

the length and breathe of a rectangle are in the ratio 2:1 . it its breadth is 20 m than is perimeter is ???? please explain ​

Answer 1

Step-by-step explanation:

let the breadth be b

so length is 2b

if b = 20m

then length =  2*20=40m

perimeter = 2{l+b}

                    2{40+20}

                     2*60

                    120

the perimeter of the rectangle is 120m.
