How would i get the area of a diagonal rectangle.

You need to find the distance between the points (10,0) and (15,5) This will give you the width. The length is the distance from (10,0) and (20,-10). The area = width * length.

width =  sqrt ( (5-0)^2 + (15-10)^2)

= sqrt50

length = sqrt ((-10-0)^2 + (20-10)^2)

=  sqrt 200

So the area of the rectangle = sqrt 200 * sqrt 50

= 10 sqrt2 * 5 sqrt2

= 10*5*2

= 100  square unts  Answer

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
