The length of a rectangle is twice the width. the perimeter is 48 inches 2a: find the dimensions of the rectangle. 2b: find the area of the rectangle.

x=16;y=8

Step-by-step explanation:

x=length

y=width

the length of a rectangle is twice the width

so,

x=2y(1)

the perimeter is 48 inches

so,

2(x+y)=48

x+y=24(2)

2y+y=24        [from 1]

y=8(2)

so

x=2.8        [from 1 &2]

x=16

good luck!
