Tian's rectangular living room floor measures 15 feet by 18 feet .
A. How many square feet of carpet will Tina need to cover the entire floor ?

270 square feet

Step-by-step explanation:

To get how much carpet you will need, you need to find the area of the floor. To find the area, you multiply the sides together, so .

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
