Please answer asap! The length of a rectangle is twice its width. If the perimeter of the rectangle is 48 ft , find its length and width of the rectangle.

length=16ft

width= 8 ft

Step-by-step explanation:

Perimeter of rectangle = P = 48ft

Length = 2w

Width = w

Perimeter of rectangle = 2(Length+Width)

48=2(2w+w)

48=2(3w)

48=6w

48/6=6w/6

8=w

w=8ft

Length = 2w = 2(8)=16ft

Width = w = 8ft

The length is 16 ft and the width is 8ft

Step-by-step explanation:

48 divided by 4 = 12

one has to be double of the other

12-4=8

12-4=8

12+4=16

12+4=16

16+16+8+8=48

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

%40
