Item 58 You design a treehouse using a coordinate plane in which the coordinates are measured in feet. The vertices of the floor are (-1,-1 )t(7,-1) (7,6), and (-1,6). Find the perimeter and the area of the floor.

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
