It takes 1 workday to paint 19 of a house. At this rate, how many workdays will it take to complete painting the whole house? PLEASE ANSWER QUICK

Option c) 80 centimeters by 120 centimeters is correct. if 4 centimeters represents 25 feet, 500/25 equals 20 sets of 25, so 500 feet would be represented by 20 sets of 4 (20x4) or 80 centimeters. 750 is half again 500 (500/2 equals 250 and 500 plus 250 equals 750). half of 80 is 40, and 80 plus 40 is 120.
