I was hoping you could go over my paragraph proofs for questions (b) and (c).

(b) The perimeter of the rectangle is the sum of the measurements of all sides. Rectangle 1 should be, 2(W+L)=2(x+y). Rectangle 2 should be, 2(W+L)=2(2x+2y)=2(2(x+y)=4(x+y)=2[2(x+y)]. Which then simplifies to 2 times the perimeter of Rectangle 1.

(c) The area of a rectangle is the product of the lengths of two sides. To find Rectangle 1’s area you would multiply (x)(y). For Rectangle 2 the area formula would be (kx)(ky)=k^2*xy. Which would make Rectangle 2 k^2 times the area of Rectangle 1.

My other paragraph proof for (b) was...But didn't know if it as correct.:

The perimeter of the rectangle is the sum of the measurements of all sides. Rectangle 1 should be, Perimeter(Recangle 1)=2x+2y. Rectangle 2 should be, Perimeter(Recangle 2)=2kx+2ky. Which then simplifies to 2 times the k(2x+2y)=k(Perimeter of Rectangle 1).

Sorry to bother you with this. Thank You!
