Question

A square with each side measuring 10 inches has a red piece x inches long removed and a blue piece x inches long added as shown in the figure below. Find the area of the white and blue rectangle.

Answer 1

i tried (10+x)-(10-x) but i keep getting 2x and that doesn't seem right

Answer 2

i would love a picture, it is only fair since you get one ?

Answer 3

i have no idea
i would assume you would have to do something along the lines of figuring out the area and perimeter in terms of x?

Answer 4

new width = 10-x
new length = 10+x
area = (10-x)(10+x)

Answer 5

why x=10?

Answer 6

ignore me :P

Answer 7

ok

Answer 8

thanks

Answer 9

so 100-x^2 is the answer?

Answer 10

(10-x)(10+x)
= 100-x^2

Answer 11

yes!

Answer 12

ok
