Step-by-step explanation:

Area

The area of the entire rectangle that is 4b by is found using A = l*w. If w=4b and l= then the area is:

However there is a cutout in the middle. Find the area of the cut out and subtract from the total area.

The cutout is by b. So the area is:

Subtract

Perimeter

The perimeter is the distance around the entire figure. To find it, add each side length. Then add like terms together.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

b
