Answer 2

Answer:

Width of a rectangle is 3.33

Step-by-step explanation:

let the width of a rectangle is X

then A.T.Q. the length of a rectangle is 2X

perimeter of a rectangle = 20

now, we know that

perimeter of rectangle = 2 (length+width)

20 = 2 ( 2X + X)

20 = 2 (3X)

3X = 20 ÷ 2

3X = 10

X = 10 ÷ 3

X = 3.33

so, the width of a rectangle is 3.33
