@amistre64 Could you help me? I have no idea what this is even asking

anonymous · Answer

the last part is cut off......but there are three parts and it helps to draw a picture... 
originally you have a square with length and width both k. you should know to find area is lengthxwidth. so area of original is k*k

first, there was size added. it says p units to both length and width . so now the length and width are both (k+p)*(k+p). From that you should find the area and compare it to the original

anonymous · Answer

that is the are. both length and width are now p+k...... so the area is (p+k)(p+k)

anonymous · Answer

For the second part... we are back at the original cloth... and she REMOVED P units from each side. Thus our sides are now equal to  k-p.... the area is then (k-p)*(k-p). you can find it and compare the area to the original

i cant read the third part

anonymous · Answer

I wouldve never figured that out, thank you! 
the third part is Jackie cut off a strip of cloth from one side of the tablecloth and pasted the strip on an adjacent side of the tablecloth to increase its length by p units and decrease its width by p units. What will be the change in the area of the table cloth? Show your work

ok... so from what we JUST figured out for those two... it is similar except one side has grown and one side has shrunk. so now it is NOT a square but a rectangle with length of (k+p) and a width of (k-p) ..... so area is (k+p)(k-p)
