The base of a rectangle is 7 more than its height. if the area of the rectangle is
44 square centimeters, what is its perimeter?

Step-by-step explanation:

Let the height of the rectangle = x cm

The base of rectangle = x + 7

Area = 44 Sq.cm

base * height = 44

(x+7)* x = 44

x² + 7x = 44

x² + 7x - 44 = 0

x² - 4x + 11x - 44 = 0

x(x-4) + 11(x-4) = 0

(x-4)(x+11) = 0

x-4 = 0 or x+11 = 0

x = 4   0r x = -11

x =4 ( measurement cannot be in negative value)

Height = 4 cm

Base = 4 + 7 = 11cm

Perimeter = 2 * (base + height)

                 = 2*( 11+4) = 2*15

                 = 30 cm

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
