Determine the perimeter and area of a rectangle that has a width of 6 inches and a length of 8 inches.
Using a ratio of 1:2, draw a similar rectangle that is double the width and length of the first shape. Determine the perimeter and area of this new rectangle.
Draw one more rectangle using a ratio of 1:3 (a rectangle that is triple the width and length of the original shape).

P = 2L + 2W
P = (2 * 8) + (2 * 6)
P = 16 + 12
P = 28
A = L * W
A = 6 * 8
A = 48 sq. inches

Thank you so much. I got that part but I don't understand using the ratio 1:2.
