Answer:
x = 13 1/2 days
Step-by-step explanation:
1/2 acre 2 1/4 acre
------------ = -------------------------
3 days x days
using cross products
1/2 * x = 2 1/4 * 3
change 2 1/4 to an improper fraction (4*2+1)/4 =9/4
1/2 x = 9/4*3
1/2x = 27/4
multiply each side by 2
2 * 1/2 x = 27/4 * 2
x = 27/2
change back to a mixed number
x = 13 1/2

a dilation with a scale factor of 4, is multiplication by 4 each side, so we need the measure of the side CD and then multiply by 4 to find C'D'
we can notice tht length of CD, is 3 squares,multiplying by 4 the new length is 3x4= 1 2 squares
