A rectangle has dimensions 7 ft x 12 ft. Which of the dimensions describe a rectangle that is similar to this rectangle?
A) 5 ft x 7 ft
B) 14 ft x 36 ft
C) 21 ft x 36 ft
D) 21 ft x 48 ft

C)21 ft x 36 ft

Step-by-step explanation:

Because 7 * 3 = 21 ft & 12 * 3 = 36 ft

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
